Don’t choose a cool profession. Make your calling/profession cool.
Work on perfecting your craft everyday.
Pay attention to your health. Remember, the abilities that we easily take for granted can become hopelessly difficult when we are sick.
The pursuit of professionalism should include this goal: machine-like accuracy and consistency.
When recalling past failures and unfair treatments and betrayals, ask: what did i learn? How exactly do these help prepare me for larger success in the future?
