And science backs up the concept. Psychotherapist Noel McDermott says using a hype folder can act as a form of “cognitive behavioural therapy”.

“Positive examples of our real-world impact are well-researched ways to help build esteem and confidence, and to reduce anxiety and depression,” he tells Stylist. “In cognitive behavioural therapy there is a cognitive restructuring process called balanced thinking where we take a ‘hot’ thought that contains negative messaging – for example: ‘I’m going to get fired cause I’m rubbish at my job.’ And we balance thoughts so they don’t trigger an uncomfortable emotional response. With a hype folder, we can have balancing real-world examples to challenge the hot thought and reduce our emotional response, so it stops upsetting us.”

Hype folders can also help to manage stress. “Practising feeling good about ourselves via affirmative thinking is good for our health overall,” McDermott explains. “Learning to use a positive feeling state is learning to utilise our body’s chemistry in our favour. We can have stress hormones or reward hormones and we have a lot of choice about which predominates in our mind. Stress hormones will degrade our psychological and physical wellbeing and reward hormones will enhance both. Learning to be able to manage our thinking to make ourselves feel good is a very valuable tool, so hype folders can very much help in this endeavour.”

Finally, McDermott also notes there is another psychological method to help us boost self-esteem and our sense of worth that can work in tandem with a hype folder.

“Exposing ourselves to and overcoming seemingly small things that overwhelm us very much helps with improving our esteem,” he says. “For example, do you dread having to return faulty goods or complaining about poor service? Practising how to do these things successfully can have outsized emotional benefits. Why? Because esteem comes from being able to do what we fear to do, not what we know to do.”
