Please just make stuff
Anything. Whittle a stick to a point not for any reason in particular. Hem a shirt. Write a shitty poem, and then more, and like it. Make a stupid song and sing it with your friends. Draw caricatures of anything. Paint the color of the paint you're using.
Try in earnest at least for it all. You possess an infinitely creative soul; please remember to use it. Just don't think you can't or are incapable of doing as much. It is vitally important that you do, regardless of your opinion on what you produce or the nature of your ability. To make anything is good.
