Here is an excerpt from Great Grandmaster Tae Yun Kim‘s book, The Silent Master:
I mentioned before that you might be surprised how much energy it takes to change your life. Since bad habits and negative thinking build up such momentum over time, only your will power can break through and give you the push to get started and to stay on course.
When you realize this, you may be thinking yourself discovery journey is over! “I have no will power,” a lot of people say. To this I say: yes, you do. In fact, you’re using your will power right now to pursue all the bad habits you presently have. No one orders you to hide when it’s time to meet new people. No one makes you fail the exam you didn’t study for. You do these things by yourself, with the power of your own will. What you need to do is learn to use your will power constructively and positively.
