Do you think this is dumb?

In your case there's nothing to keep to myself. Not dumb!! I don't know your age and it doesn't matter. Bet I'm a lot older than you, and I'll never stop drawing and painting until I just can't do it any more. I'm very senior and do not look forward to the day when I can no longer push a pencil around or drag a paintbrush. I envy you - sounds like you have a lot of originality, which I don't. Don't stop what you're doing.
