" you can become successful with less discipline than you think, for one simple reason: success is about doing the right thing, not about doing everything right. The trick to success is to choose the right habit and bring just enough discipline to establish it. That’s it. That’s all the discipline you need. As this habit becomes part of your life, you’ll start looking like a disciplined person, but you won’t be one. What you will be is someone who has something regularly working for you because you regularly worked on it. You’ll be a person who used selected discipline to build a powerful habit. "
