Quote by John Carmack

"Focus is a luxury for people who can afford to give up opportunities."

"The most important thing is the way you fall."

"Ideas are worthless. Execution is everything."

"It is inevitable that we will leave some bugs for the next guy."

"Face your fears with courage."

"You can't live your life in fear."

"Snakes. Why'd it have to be snakes?"

"Fear is just another obstacle to overcome."
