Self-disciplined people are not all outstanding, but nearly all outstanding people are self-disciplined people. Self-discipline is pivotal to happiness and usefulness. It is the master of all the virtues, and has its root in self-respect.
Self-discipline requires self-knowledge and an accurate assessment of your current abilities.
自律要求自我認識以及對自己能力的正確評估。
First, self-knowledge is a preface to self-control. A fair amount of self-examination is good; too much leads to morbidness; too little conducts to careless and hasty action.
Second, the man who would succeed in any great undertaking must hold all his faculties under perfect control; they must be disciplined and drilled until they quickly and cheerfully obey the will.
We all know that self-discipline is in fact self-management. If you want to get slim, you need to manage your appetite. If you want to succeed, you need to manage your heart. Think of your mind as a reservoir in which you have been storing up all the potential power. You will now learn to release those power in precise quantities and specific directions. This is the essence of self-discipline.
So set your goal and write down your reasons for them. Establish a list for your daily work and life, and execute them out without mercy. This is not sacrificing your freedom. This is freedom.
Only in self-discipline can you stop being a slave of all the trivial things in your life. Only in self-discipline can you achieve the success you desire.
