Dublin is an inspirational setting. Past and present stories of resilience are written into the city’s fabric and carried by its people. In Merrion Square, there is a unique totem to hopefulness that stands out more than most, the Oscar Wilde memorial monument honouring one of Ireland’s lauded poets and playwrights. Memorably, in Lady Windermere’s Fan, Wilde wrote, ‘We are all in the gutter, but some of us are looking at the stars.’ The power of these lines goes beyond their poetics, positivity, or universality because they touch upon something more profound, the hidden strength of the human psyche.
Optimism is a source of scientific inquiry and has been studied extensively to ascertain its physical and psychological benefits. These studies are ongoing, but optimism supplements better health. Research shows that it is associated with contributive behaviours such as being physically active and not smoking (Boehm et al., 2018), a healthy diet score (Hingle et al., 2014), better sleep quality (Sims et al., 2019), and higher composite cardiovascular health scores (ibid, see also Hernandez et al., 2015, 2018). We still need to find out how and why optimism scientifically influences these diagnostics, but we know it yields clear-cut results with empirical certainty.
Other points of influence that may not affect you daily but are impacted by optimism include high capacities for surviving a disease, particularly heart disease (Tindle et al., 2009). Studies also correlate optimism with improved recovery from surgery, broader immunity, positive cancer outcomes, positive pregnancy outcomes, increased pain tolerance, and more stability amid other health concerns. In all of these metrics, those with an optimistic outlook had better results than those who were pessimistic.
Even more impressive is optimism’s association with overall health and longevity. Having a positive outlook is predictive of a greater quality of life (James et al., 2019) and a lower death rate (Rozanski et al., 2019). Optimistic people—whether by disposition, purposeful mindset, or praxis—lead healthier longer lives. Although living better or ageing gracefully does not determine success, health is essential if we approach success as a web of holistic factors related to achieving maximum performance. The evidence is unequivocal; having a positive outlook can boost your physical robustness and provide the platform from which you will most likely achieve consistent success.
What is more, optimism is blind. The data suggests that optimism is a boon regardless of demographic factors such as income level or general health. Maybe this should be less surprising since the positive thinking associated with optimism is also attributed to effective stress management. Stress may not be equal, but it is universal.
Mental health and mentality
The World Health Organization (WHO) defines mental health as a ‘state of mental well-being that enables people to cope with the stresses of life, realise their abilities, learn well and work well, and contribute to their community. It is an integral component of health and well-being that underpins our individual and collective abilities to make decisions, build relationships and shape the world we live in.’ Critically, WHO’s definition includes this addendum, ‘Mental health is more than the absence of mental disorders.’ It is more variable and directly assists our health continuum, which, by extension, aids our self-maintenance and performance.
Optimism is intersectional within the body and mind realms it inhabits. It supports psychological well-being, especially during uncertain times when the risk of deteriorating mental health rises. As recently as last year, a statement made by the American Heart Association (AHA) declared, ‘Positive psychological health is also multifaceted and may be characterised by a sense of optimism [my italics], a sense of purpose, gratitude, resilience, positive affect (i.e., positive emotion), and happiness.’
Moreover, mental health’s positive emotional and social dimensions help us foster productive relationships personally and professionally. Being aware of the many unseen components of mental health can help us generate empathetic responses to problems that arise with staff. None of this comes as intuitively as you might presuppose.
Our most recent 1% podcast with Dr Libby Sander identified some gaps in professional culture regarding expectations, an overemphasis upon certain kinds of productivity, boundary setting, burnout, the role of emotional intelligence in leadership, and even the physical space that we work in. I must reiterate Dr Sander’s points. Ultimately, everything is a possible component of our successes and our failures. It is up to us to harness them for our means rather than leave them to become something to be dealt with later.
Pushing out pessimism
Optimism’s counter-force is a balanced critical perspective, not pessimism. The AHA statement outlines that pessimism may be understood as ‘the tendency to expect negative outcomes or by the tendency to routinely explain events in a negative way.’ Just as optimism engenders varied physical and mental health benefits, pessimism is linked to unwanted outcomes such as cardiovascular risk and hopelessness (Pänkäläinen et al., 2019).
Optimism is an active process. Harvard Health Publishing explains that optimism is divided into ‘dispositional’ or ‘explanatory’ modes. Regarding the latter, being optimistic does not mean ignoring less pleasant situations. Accept them and approach unpleasantness more positively and productively. Imagine the best or at least the best possible scenario, not the worst. Be confident you can make it happen. Reconfiguring your visions to even moderately desirable outcomes is beneficial. On these terms, optimism is often a form of honest appraisal and reframing when unexpected or unwanted events occur.
Positivity often begins with self-talk. The thoughts within us can uplift or inhibit us. Much self-talk comes from logic and reason; listen to it. Equally, self-talk comes from misconceptions we create from doubt, if not fear, a lack of information, impossible or unrealistic expectations, and preconceived ideas of what will happen to or against us. These thoughts are not reasonable. Quiet them. Cynicism and downbeat steadfastness are not virtues and spread quickly in a pressurised workplace. If you tend to be pessimistic, you can still learn positive thinking skills. Optimism is part mind state, part mental practice. Identify negative thinking, and try to reduce it. Examples include filtering out what is going well and emphasising what is not, personalising setbacks or making them your fault when they are not, blaming others when it is your fault, expecting the worst possible outcome as opposed to planning for it, magnifying minor setbacks, setting impossible standards so that disappointment becomes a fait accompli, and adopting a polarising view of things as ‘good’ or ‘bad,’ whereby leaving no room for nuance. Envision what you want to happen next or understand what remains possible and focus strictly on actualising it.
I began this article with a personal flourish intentionally. We are human, and success is not mechanical or natural. It is earned and does not typically follow a linear or smooth path. Similarly, goals require commitment, and so does our physical and mental health. If these elements in any way become a hindrance, our long-term professional performance will likely dip. Without question, our ability to reach and maintain maximal performance levels will be diminished.
In a piece fittingly titled, ‘The Optimism of Uncertainty, Howard Zinn reminds us that ‘To be hopeful in bad times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty but also of compassion, sacrifice, courage, and kindness. What we choose to emphasise in this complex history will determine our lives.’ If nothing else, science backs up that very last point incontrovertibly. Zinn continues, ‘The future is an infinite succession of presents, and to live now as we think human beings should live, in defiance of all that is bad around us, is itself a marvellous victory.’
At this moment in time, the global context is bleak. War, economic, and energy crises loom overhead. More things are more uncertain than they have been for a while. All of which impact our work and our lives. We must take nothing for granted and care for our bodies and minds. We may not know why, but optimism significantly helps us do so.
