Discipline: Be Passionate
I don't believe I've gone for a week without training, practice, or at least working-out in 15 years. (I can at least verify 7.) I used to hear comments about how I was so "disciplined" or "dedicated" or "motivated" or some other adjective that people use as hashtags for their Instagram gym photos these days. Sure, sometimes I am, but that doesn't really account for 15 years. Motivation barely gets me through 6 weeks. There has to be something deeper that drives you.
Peace is a lie, there is only passion. Through passion, I gain strength. Through strength, I gain power. Through power, I gain victory. Through victory, my chains are broken. The Force shall free me.
