I feel like I have to be in the correct frame of mind, but often find that once I sit and get to it, the act puts me there. I can't just start new projects because I don't feel like working on the "unfun" part of whatever project I am working on. My motto is "just do it and you won't ever have to worry about it again". I absolutely hate UFO's, they drive me crazy and I feel like I can't work on anything (and I mean anything) else until they are finished.
