Discipline your mind
There are two ways of discipline in your mind. One is by learning, and the other is figuring out how to control your thoughts more effectively. I find that it’s best if these two things are done together. As you learn more, especially if you are learning about what is good, you’ll be there to focus your mind on better things. While you’re doing that, you should find ways to push bad thoughts out of your mind and hone in on good thoughts.
Discipline your actions
Now, it’s time to put your learning to work. You have to begin acting out what is good and learning how to do it better. You have to find a way to discipline yourself in all areas of your life: physical, emotional, intellectual, and spiritual. For men, it’s often easiest to start with the physical because that actually begins to wire your body the right way to take on other challenges.
Discipline your schedule
Once you begin to act out positive things, it’s time to find a way to do them more regularly. Finding time early in the morning or late at night depending on what kind of person you are to read, work out, and grow spiritually is important.
