The ability to discipline yourself to delay gratification in the short term in order to enjoy greater rewards in the long term, is the indispensable prerequisite for success.
You cannot control what happens to you, but you can control your attitude toward what happens to you, and in that, you will be mastering change rather than allowing it to master you.
Your ability to discipline yourself to set clear goals, and then to work toward them every day, will do more to guarantee your success than any other single factor.
