The only guarantee for failure is to stop trying

I tell a person, "If I could go home with you tomorrow and you and I could spend the day together from maybe 8:00 to 6:00, and we went out to a restaurant at 6:30, I could tell you with a high degree of accuracy how successful you're going to be." That's huge because I'm just going to look and see, what kind of attitude do you have, how do you relate to people, how well do you prioritize your life? I'm going to see all of those things in the process of a day.

Leaders attract potential leaders.

We all stand on the shoulders of the past generation.

If you keep your mind active, regularly take on mental challenges, and continually think about the right things, you will develop the disciplined thinking that will help you with whatever you endeavor to do.

If you do the things you need to do when you need to do them, then someday you can do the things you want do when you want to do them.

If you are too attached to your own thinking and how everything is done now, then nothing will change for the better.
