「只有在生活中紀律嚴明的人才是自由的。如果缺乏紀律，只會成為情緒和激情的奴隸。」(Only the disciplined ones in life are free. If you are undisciplined, you are a slave to your moods and your passions.) — Eliud Kipchoge
“A vital part of the happiness formula is self-discipline. Whoever conquers himself knows deep happiness that fills the heart with joy.” — Norman Vincent Peale
Discipline is about what you do on the days when you feel like crap.
「自律」只是外在的表面結果，「自願」才是內在真正的驅動力。
Discipline now, freedom later. Discipline equals freedom.
Discipline eats motivation for breakfast.
Excellence translates across disciplines.
Winners are not people who never fail, but people who never quit. Remember: “If you quit now, you will soon be back to where you started. And when you started, you will be desperately wishing to be where you are right now.”
