Work 70 hours/week, calmly

This is massive action.
But when you start you will go between 2 extremes:

1. Think calmly/rationally for 40 hours per week.
2. Work frantically for 70 hours per week.

You must learn the prerequisite first of how to think rationally.

And then feel the urge to work 70 hours per week.

If you begin to feel frustrated/stressed that the next step is being blocked, you must step away immediately.
Always come from a place of curiosity.
Take 20 minutes, write your thoughts down.

If the next step is still blocked, ask for help.
