Key ideas based on Brian Johnson's PhilosopherNotes:
Forces that drive the universe function on a much smaller level. The small things add up to big things (i.e.: the power of persistent Habit).
The only way to take it back is to identify what’s really important to you and pursue it with every last ounce of energy
A great life does not come without injury.
Decide what’s worthy of you in this one precious life of yours and GO ALL IN.
An "All In" level of commitment invites a ton of pain. We need to have the desire to absorb it to achieve our goals.
We need to start seeing problems as gifts. Fuel for growth.
