Success requires hard work and self-discipline. With self-discipline, anyone gain self-confidence and achieve success. Perhaps you lack self-discipline in certain areas and assume "that's just the way I am." Perhaps some people are born with natural qualities and abilities that make self-discipline easy for them, but most successful people are made not born, through hard work and self-development.
The fact is you can develop whatever qualities you consider desirable and necessary for your success. For some people, it will be easy, and for others it will take more time and effort. But each person has the inborn ability to shape his character in a positive way. All that is required are clear intentions and a determination to press forward through the difficulties, resistance and setbacks.
Develop the discipline you desire. The process of developing discipline is simple, if not easy. First, decide upon the discipline that will be most helpful to you right now. Don't try to change several things about yourself at once, no matter how attractive and desirable they may be. Focus instead on the development of a single discipline until it is locked in and becomes a part of your personality. Then you can move on to the development of the next discipline.
Fortunately, every act of discipline strengthens and reinforces other disciplines. And acquiring a discipline increases your self-confidence in yourself, making additional disciplines easier to achieve. But you must be vigilant. Everything counts!
