^ yeah same
I blast music with my stereo when I'm in my room working out with weights, and when I'm skiing I just turn up the music real loud, wait till a good part, and go. Count down, "1...2..3...go!" and if I don't go I know I can't do it right then. So for skiing I just try to point and go.
For stretching...just get a regular routine. Reward yourself afterwards with something.
