Loosen up, will you?
I have felt the need to loosen up a bit with my brush strokes. So lately I've been experimenting with a less defined stroke, and bigger brushes. I have found that it takes all my might to STOP, and put the brush down! (I literally have to tell myself that: Stop and put the brush down Breten!) Sometimes I feel like the painting isn't even done, but I must resist the urge, and just let it be as more of a vague suggestion, rather than put in every little detail I can think of.
Somehow, I can equate this to over thinking. Have you ever thought about some issue so much that you made a much bigger deal of it that it actually was? When, if you just ignored it, or made light of it, life would have been so much better? Seems like the same thing to me.
