Discipline is a choice. It's simply consistently choosing the hard right over the easy wrong.

The amount of our endurance is directly proportionate to the clarity of our vision, so the practical application is we need to spend time to develop clarity of vision. What do you want your life to look like five, ten or fifteen years from now? Oftentimes, it's not so much a lack of discipline but a lack of vision.

One of the biggest ways we lose time is not knowing where we’re going next.

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.

You multiply your time by spending time on things today that will give you more time tomorrow.

The most self-disciplined people in the world aren't born with it, but at one point they start to think differently about self discipline. Easy, short-term choices lead to different long-term consequences. Difficult short-term choices lead to easy long-term consequences. What we thought was the easy way led to a much more difficult life. I think that motivation is sort of like a unicorn that people chance like a magic pill that will make them suddenly want to work hard. It's not out there.

There is no such thing as time management; there is only self-management.
