It takes the same kinds of things to master the craft of discipline:
Repeated practice
Single-minded devotion to the purpose
Continual learning
Care
A craftsman masters his trade by repeated practice, with care and continual learning, with devotion to the purpose.
Dig Deep
Choosing to dig deep and say more, though, is where both risk and reward live.
Diary
The trick to a daily diary is to “record, don’t recall”. You’ll forget things that you wanted to remember, so take notes and organize them later. That’s how I’ve managed to keep my diary going.
— Masazo Takenami, a man in his nineties who has kept a sketch diary for sixty years.
