To arrive at a place called Mastery, you must commit to daily and rigorous practice. Enjoy practising your craft for its own sake without turning your attention to your ultimate destination. Understand, once and for all, that the journey is as important as the destination.

If you're not scared a lot you're not doing very much.
Change is hardest at the beginning, messiest in the middle and best at the end.
