I've found that if you can create a permanent habit out of your self-discipline act, it doesn't feel a like a discipline measure anymore. The discipline act feels more like a way of living after few weeks of repetition. So keep doing your "push-ups" as long as you end up liking them and get used to them. But you're absolutely right, you have to have strength to push trough the times when you have difficulties to maintain your daily tasks on your way to success. 💪😎
