A good way to tap into your creativity is to throw yourself into something you’ve never done before, just for the hell of it. Make your own wrapping paper. Draw a self-portrait. Buy an unfamiliar vegetable, then go home and prepare it.
Experimenting with a new activity (quickly, without dithering beforehand) is useful because it builds confidence. It shifts our mindset for thinking you need to acquire a skill to knowing you have a way to activate one – or several
You might even realize you’re better at the new activity than you thought you’d be. But if not, and your first go is a disaster, you’ll know what to try next time, and that’s information you would not have had if you didn’t try.
