To become the kind of person you want to become, you've got to have discipline. It's easier to keep to your standards 100 percent of the time versus 98 percent of the time.

In our personal lives, we have a lot of businesses going on. I have a profession, I'm a father, a spouse, a good member of my community. How much of my time and energy can I allocate to each of those things? What I allocate becomes the strategy I have for my family, and everything else.

Most people have never thought through how they're going to allocate their time. You need to make a decision in advance.
