Agnes Martin is one of my favorite painters. Her advice for how to make progress in life ties in nicely with the articles I posted on options, gusto, and blogging.
To progress in life you must give up the things you do not like. Give up doing the things that you do not like to do. You must find the things that you do like. The things that are acceptable to your mind.
And as long as we're on the subject (you didn't think we were even on a subject, did you?), I'm a fan of how Maciej is displaying his oil paintings. For each of his newer paintings (like this one of a West Village scene), he's documenting the progress of the work as it goes along so you can see how the painting becomes a painting.
Update: Eric writes that he uses this technique for displaying how his art progresses as well (sample).
A history and examination of paint by number. "It invited people who had never before held a paintbrush to enter a world of art and creativity."
