Resistance really takes the shape, for me, in voices in my head telling me why I can't do something or why I should put it off for another day, procrastinate for another day.

The great thing about writing about the ancient Spartans or Athenians is that so much knowledge is no longer extant that no one, except maybe a Cambridge or Oxford don, can call you out and prove you wrong.

We need to ascend beyond our own petty Resistance, our own negative self-judgment and self-sabotage, our own "I'm not worthy" mind-set.

Don't prepare, do. Don't let Resistance sucker you into wasting months on background, foundation, planning. All that can come later.

A horse must be a bit mad to be a good cavalry mount, and its rider must be completely so.

Defeating Resistance is like giving birth. It seems absolutely impossible until you remember that women have been pulling it off successfully, with support and without, for fifty million years.

The athlete knows the day will never come when he wakes up pain-free. He has to play hurt.
