Why do people paint?

I think anyone who has a  little time would benefit from art classes even though I found it terrifying.Learning anything new makes us anxious.And there was a rude ex-teacher  who was a pupil who would make nasty comments  on my efforts! Even so,I learned more than I thought but have not spent  enough time on it as writing takes my attention more.

I do notice now my efforts are often humorous like this church below.
