Self-development is the only thing that keeps a person from burning out. We all have many needs - the need for certainty, the need for variety, the need for significance, and the need for connection. But, ultimately, we must grow, and we must contribute in a meaningful way in order to feel fulfilled.

You want to know the biggest illusion about success? That it's like a pinnacle to be climbed, a thing to be possessed, or a static result to be achieved. If you want to succeed, if you want to achieve all your outcomes, you have to think of success as a process, a way of life, a habit of mind, a strategy for life.

Success leaves clues, but they must be acted upon.

Business is a spiritual pursuit. Your business will not grow unless you grow as a person

Any time you sincerely want to make a change, the first thing you must do is to raise your standards. When people ask me what really changed my life eight years ago, I tell them that absolutely the most important thin was changing what I demanded of myself. I wrote down all the things I would no longer accept in my life, all the things I would no longer tolerate, and all the things that I aspired to becoming.

When it looks impossible and you are ready to quit, victory is near!

It doesn't matter what you achieve, if you don't keep growing you'll feel dead.
