Do you see a cup half full or half empty? This question can seem trivial, but it actually can tell a lot about the way you see circumstances in life and, possibly, the way you feel most of the time. Research shows that people who see a cup as half full, a.k.a optimists, tend to have higher levels of happiness, perseverance, achievement, and health (Peterson, 2000, p. 47) compared to pessimists.
Additionally, there is evidence that optimistic people are more likely to take proactive steps when it comes to their health, while pessimism is somewhat related to health-damaging behaviours. Accordingly, a positive attitude is related to higher levels of physical and mental health, increased life expectancy, success at the workplace and better coping strategies.
Although pessimists would say that optimism is the same as denial and oversimplification, and having a positive attitude is dangerous because these individuals will end up disappointed and hurt. However, research has strong evidence against those statements. As a matter of fact, the behavioural patterns of optimists appear to provide models of living for others to learn from. After all, increased life expectancy and health, as well as being successful and happy and making people around us feel the same way is what really matters in the end.
So, if being positive is so beneficial for happiness, can we somehow incorporate it into our lives? The answer is YES, you definitely can.
Learning Positive Attitude
Becoming optimistic and training yourself to look at the bright side takes work and discipline. If you tend to see things negatively, it will take some time to make optimism a thinking habit. But once you do, you’ll definitely notice the change in the way you feel and act. So, what should you do?
Notice Your Negative Thinking Patterns
Listen to your words and your thoughts. The longer you listen, the more you’ll recognize negative assumptions and conclusions. Catch yourself doing that and try to challenge those negative thoughts. Do you have enough evidence to support those statements? Where do you draw that pessimistic conclusion from? Try replacing these negative beliefs with positive, or at least neutral ones.
Give Yourself and Others Positive Feedback
Sharing positive feedback and genuine appreciation with others doesn’t just strengthen relationships—it has measurable benefits for our own psychological well-being. Research shows that expressing gratitude activates brain regions associated with dopamine release, enhancing mood and motivation (Zahn et al., 2008). Acts of appreciation also stimulate the release of oxytocin, a neurochemical linked with bonding and reduced stress, which deepens our sense of connection and safety with others (Kosfeld et al., 2005). Studies have further found that regularly practicing gratitude can shift our cognitive patterns toward greater optimism and resilience, while lowering symptoms of depression and anxiety (Emmons & McCullough, 2003). In this way, expressing appreciation outward creates a profound inward shift—supporting emotional health, strengthening neural pathways for positivity, and nurturing a more grounded, connected version of ourselves.
Be Grateful
Practicing gratitude has been shown to create measurable changes in the brain that support emotional regulation, resilience, and overall well-being. Neuroscience research demonstrates that gratitude activates the medial prefrontal cortex—an area involved in decision-making, reward processing, and emotional regulation—which helps strengthen neural pathways associated with positive thinking (Zahn et al., 2008). Expressing gratitude also increases activity in the brain’s reward circuitry, triggering the release of dopamine, a neurotransmitter linked with motivation and pleasure. Over time, this repeated activation can help shift our baseline toward greater optimism, reduce stress, and improve long-term psychological health. In this way, gratitude doesn’t just feel good—it literally changes the brain in ways that support healthier emotional functioning.
