I am all about practicality And action. Theories and “what-ifs” are not a world I live in. I live in reality.
And reality is based upon what you do. Not what you say, not what you think but your actions create reality.
This is super simple. Stay disciplined on the few things you need to do every day to be successful in your life. I don't have the specifics for you. That's your job. Figure out the specifics you need to do. And then do them, every single day.
Act every day. Your future self thanks you.
