“Confidence comes from preparation. When the game is on the line, I’m not asking myself to do something I haven’t done a thousand times before…In those moments, if I look like ice-cold or not nervous, it’s because I’ve done it a thousand times before. So it’s (just) one more time.” — Kobe Bryant

“Nothing wins more often than superior preparation. Genius is usually preparation.” — Kekich Credo

“You don’t become confident by shouting affirmations in the mirror, but by having a stack of undeniable proof that you are who you say you are.” — Alex Hormozi

People are always claiming that success is a matter of luck, but as Pasteur pointed out, “Luck favors the prepared mind.” […] Many times a discussion with a person who has just done something important will produce a description of how they were led, almost step by step, to the result. It is usually based on things they had done, or intensely thought about, years ago. You succeed because you have prepared yourself with the necessary background long ago, without, of course, knowing then that it would prove to be a necessary step to success.” — Richard Hamming

“The fight is won or lost far away from the witnesses, behind the lines, in the gym and out there on the road, long before I dance under those lights.” — Muhammad Ali

自信，只能從面對並且克服「不擅長」的事裡獲得。當一個人從無到有、從0到100的過程中獲得成就感，那才是真正的自信。
