Discipline yourself to do the things you need to do when you need to do them, and the day will come when you will be able to do the things you want to do when you want to do them!
You are free to choose, but the choices you make today will determine what you have, be, and do in the tomorrow of your life.
We need to understand the difference between discipline and punishment. Punishment is what you do to someone; discipline is what you do for someone.
When I discipline myself to eat properly, live morally, exercise regularly, grow mentally and spiritually, and not put any drugs or alcohol in my body, I have given myself the freedom to be at my best, perform at my best, and reap all the rewards that go along with it.
It's absolutely true that unless you can instill discipline upon yourself, you will never be able to lead others.
Personal discipline, when it becomes a way of life in our personal, family, and career lives, will enable us to do some incredible things.
