A martial-artist friend of mine told me about an exercise his teacher had him do. For a week straight, he would have to just sit calmly on a chair or a cushion for at least an hour and envision everything he wanted to be doing and accomplishing at that very moment, but keep sitting and not doing anything at all. When you get to the point where you are so excited to do it that you can't sit anymore, go. I tried this for coding personal projects and I recommend it highly.
