The ancient-Greek commandment Know thyself turns out to be a great modern way to become happier, more empathetic, and more successful.

1. Stop protecting yourself.
Training yourself to accept the regular, systematic physical discomfort of a tough workout in the gym builds strength and endurance.

2. Embrace a change narrative.

Those who have a mindset oriented to aggressive improvement are actually impatient with empty compliments; they prefer criticism, and see it as a secret weapon they need to improve even more.

3. Decide what to change and get started.

In a nutshell, practice acting like a better person and you will actually start to become that person.

Knowing what I was not ultimately helped me be who I could be.
