 Stop thinking about it, start. You just gotta start. Once you start, you don't quit. Even when you don't feel like getting up and working out and training, you don't feel like going to that development session to train, you do it anyway. It's about discipline, not motivation. Motivation wanes, you will not always be motivated, but the discipline is what keeps you going after it. On the days you don't wanna train, you need to do it anyway.
