Positive psychology or toxic positivity — can personal development really help us feel better?

It is often associated with motivational slogans and brightly coloured books that promise a better life. But beyond the stereotypes, positive psychology and personal development have some serious insights to offer. So, does it really work?

Let’s be honest: the term ‘positive psychology’ can sometimes make people cringe. And frankly, that’s understandable. Between Instagram quotes, coaches and gurus promising a transformation in 30 days, and constant exhortations to ‘look on the bright side’, the field has at times been co-opted by a form of ‘happiness marketing’ that’s rather removed from our reality.

But here’s the thing: as a professional trained in these tools, reducing positive psychology to this is a bit like judging nutrition by miracle diets. The underlying principles are sound. It’s how we use them that can go astray.

After all, just because a tool can be misused doesn’t mean we should throw it away. But it is precisely because it can be misused that we need to understand its scope and limitations.

Criticisms that deserve to be heard

The most significant criticism is that of toxic positivity. You’ve probably heard of it: that tendency to want to turn every difficult experience into a ‘life lesson’, to downplay suffering with a big smile and a ‘but think of everything you have!’ When ‘think positive’ becomes a social imperative, it doesn’t liberate — it makes you feel guilty. Those who can’t manage it end up feeling ashamed for not being positive enough. And that’s when things can really go downhill.

There is also a more structural criticism: by placing such a strong emphasis on a person’s internal resources, positive psychology may overlook the social, economic and systemic factors that contribute to unhappiness. This constant ‘love yourself first’ mantra is all well and good, but sometimes the problem isn’t in the mind — it lies in one’s living conditions.

So, what exactly are the practical benefits of personal development and positive psychology?

Because, yes, there are. And they’ve been documented. Researchers have spent decades studying what makes a life fulfilling — not just symptom-free, but truly well-lived. Here’s what consistently emerges:

• Character strengths: Identifying and utilising one’s strengths in daily life leads to lasting improvements in well-being and engagement. (Park, N., Peterson, C., & Seligman, M. E. P. (2004) — Journal of Social & Clinical Psychology)

• Flow: These moments of total absorption in an activity are linked to a deep sense of fulfilment. (Frontiers in Psychology — A Scoping Review of Flow Research (2022))

• Gratitude: Robust studies show that a regular practice of gratitude reduces anxiety and improves sleep. (Emmons & McCullough (2003) — Journal of Personality and Social Psychology)

• Resilience: It takes work. It doesn’t just happen. And the tools to develop it exist. (Liu et al. (2020) — Clinical Psychology Review (ScienceDirect)

• Meaning: Acting in line with what truly matters to you is one of the best predictors of well-being.(Boyle et al. (2009) — Psychosomatic Medicine)

• Connections: The quality of social relationships is the most consistent factor in life satisfaction. (Harvard Gazette — Over nearly 80 years)

  
  

These elements form Seligman’s PERMA model (Positive emotions, Engagement, Relationships, Meaning, Accomplishment). This is not just a wish list — it is a framework that helps us identify what is missing in our lives and work on it in practical terms, whether in therapy or outside of it.

There is also the concept of flourishing — thriving, not just the absence of suffering. It’s a significant shift in perspective. It suggests that therapy isn’t over once your symptoms have disappeared. It can also be a journey towards something.

What this changes in a therapeutic approach

This is where it gets really interesting. Coaching approaches, brief therapies and ACT (Acceptance and Commitment Therapy), for example, all share something in common with positive psychology and/or personal development: the belief that everyone already possesses the necessary resources within themselves. And that the task is to draw on them.

"Acceptance is not resignation. Cultivating what nourishes us is not wishful thinking. These two approaches complement one another."

ACT, on the other hand, does something powerful: it encourages us to embrace difficult emotions without fighting them — AND to take action towards what really matters. Positive psychology adds another piece to the puzzle: positive emotions aren’t just pleasant; they broaden our scope of action.

And the clarification of values — a cornerstone of ACT — resonates directly with research on meaning in positive psychology. Knowing what matters to you, and acting in line with that, is both the driving force behind therapeutic change and one of the best indicators of lasting well-being.

So, can personal development help you feel better?

Yes. Provided it is used wisely. Personal development in the broadest sense — books, podcasts, journaling exercises, mindfulness practices — can be a real source of support, especially for people facing mild to moderate difficulties, who are looking to get to know themselves better or to regain their momentum. That’s no small thing.

But it has its limits. It is no substitute for therapeutic support when suffering is severe. And it can even become counterproductive if it turns into the thought: “I’ve read all the books but I still can’t get better” — and therefore I’m a failure. That shift is real, and we must be wary of it.

What these approaches bring that is most valuable in clinical practice is not a list of exercises to do. It is an attitude: that of the therapist who believes that the person in front of them is fundamentally competent, capable of change, and that the work consists of supporting the emergence of solutions — not of making a definitive diagnosis of what is wrong.

This stance does not deny suffering. It simply refuses to make it the only possible reality.

Most of the criticism levelled at personal development is actually directed at the ways it has been misused: at its exploitation for marketing purposes, and at unqualified coaches. It is not the discipline itself that is at fault. When properly integrated into a rigorous yet compassionate practice, I believe it remains a valuable tool — because it reminds us that lasting change comes not only from fixing what’s broken, but also from building something new... =)
