“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

Confidence in public comes from discipline/preparation in private.

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。

Layla Shaikley

Confidence doesn’t come from believing in yourself. It comes from having done the uncomfortable thing enough times that your nervous system stops flagging it as an emergency.

Because nothing is actually hard, it’s just unfamiliar.

Difficulty is a perception your brain assigns to protect you from novelty — not an accurate measure of what you’re capable of. Every time you post, pitch, or push through something that scares you, your brain updates its prediction model. Expansion stops being coded as danger.

You don’t build confidence by thinking differently. You build it by acting before you’re ready, until the action becomes familiar enough that the threat response weakens.
