The Figure Painting workshop I just took got me thinking about motivation - how long it took me to decide myself to start painting and how I can be motivated to continue now that I started.
Here are a few resources I came across.
Put your money where your mouth is by Ben Mathis - a good reminder of how easy it is to slow yourself down and think about doing things to improve your situation instead of actually doing something about it.
Along the same line, this video of Digital Painting with Bobby Chiu is a good reminder that motivation starts within yourself. His other videos are great tutorials as well as thoughtful ramblings about creativity, motivation, and dreams.
