If you doubt yourself, make things. Writing, cooking, singing a song, even doodling on a piece of paper — anything goes. You’ll know you are still capable of creating something from scratch.
It doesn’t matter if you’re good at it or not. After all, we’re all novices at the beginning. So is an expert. A unique talent is not given; it is to be developed from raw materials within us.
Recognize that each one of us is a creative creature — without exception. Don’t be afraid of being creative. Make things every single day.
