I was reading Leo Babauta's blog where he discusses motivation and basically said that one of the best way to keep motivated is to have some sort of (good) public pressure. He recommends using online forum to talk about what you wanna accomplish, what you did etc... He gave the examples of losing weight.
Well I thought "is there any forum where musicians have some a blog or part of a forum dedicated to that?" Like sharing your goals and keep a daily report of what you practice etc...
The best thing would be a jazz forum but any forum might work.
