Atomic Habits

The problem with goals-first mentality is that you're continually putting happiness off until the next milestone. ... A systems-first mentality provides the antidote. When you fall in love with the process rather than the product, you don’t have to wait to give yourself permission to be happy. You can be satisfied anytime your system is running. And a system can be successful in many different forms, not just the one you first envision.

Progress requires unlearning. Becoming the best version of yourself requires you to continuously edit your beliefs, and to upgrade and expand your identity.

The focus should always be on becoming that type of person, not getting a particular outcome.

Anyone can have a bad performance, a bad workout, or a bad day at work. But when successful people fail, they rebound quickly. The breaking of a habit doesn’t matter if the reclaiming of it is fast.

The only way to become excellent is to be endlessly fascinated by doing the same thing over and over. You have to fall in love with boredom.
