Discipline:

farnam street:

"Anyone can do something once. Not everyone can do it consistently. Eating healthy for a meal is common. Eating healthy all week is not. Working out occasionally is common. Working out a few times a week is not. Going to bed on time is easy. Doing it for a week is not.

Positioning yourself for future success is simple but not easy. The hardest part is the discipline required to do otherwise ordinary things for an extraordinarily long period of time, even when the results are barely noticeable."
