Each day, as each situation arises, stand by your choice. If you let your emotions control your motivation, you will run into trouble. Times will arise when you don't feel like doing so and so, and you won't. You must persevere. This is where discipline comes in.
Disciplines are like good habits, only harder to form.
Discipline is being faithful to the goal you've set or to the choice you've made, regardless. So when all else fails, you don't feel like doing it - lean on the strength of your discipline. You'll find it is God. This is a lecture that my cousin will be presenting in Atlanta. I thought that y'all would get something out of it.
