Fear is a big reason. Ultra achievers don't have an attitude for overcoming fear. They just do it anyway, because they're okay with being afraid. Instead of putting energy into reducing fear, they confront it with action.

Do things you don't want to do because it is the shortest, most guaranteed path to success: what you want in your life. It's not about getting a certain amount of money or a certain type of house, but what you want your life to look like.

Success is more a matter of choice than of circumstance.

Easy short-term choices lead to difficult long-term consequences meanwhile difficult short-term choices lead to easy long-term consequences.

Creating the next level of results requires the next level of thinking.

A lot of "successful" people are tragedies, because what they've accomplished aren't the things they wanted. Intentionally create the question "how" instead of accidentally relenting to the question of "should." If I'm not intentionally choosing a good attitude, I'm almost always unintentionally choosing a negative one.

Success means doing things you don't want to do.
