The Joy of Painting with Bob Ross is the most soothing thing ever put on television. Highly recommended if you're trying to quiet your mind. There's enough process to keep you engaged, there's an affirmation or two every episode that can really pick you up, and he's got a delightful sense of humor.
My dad is a big fan of the show. Years ago he went to a painting club, inspired by the painting style of Bob Ross,
I'm not sure if was a franchise sort of thing? but he's got loads of paintings that he did at the club.
If there is a person in the world, least likely to be a painter, It's my dad!
