The most important thing I can tell you about writing or any other creative pursuit is this:
Give yourself permission to do it and don't worry about being "good" at it.
Life is short. Creativity is joyful. Just do it! Have fun. Muck about.
If you stick it out, you can get good at it over time, if that's important to you — but it doesn't have to be.
You can just play with creativity for the pure joy of it, too.
If it brings you joy, do it.
