Quote from The Dip — Seth Godin

“Seven Reasons You Might Fail to Become the Best in the World - You run out of time (and quit) - You run out of money (and quit) - You get scared (and quit) - You're not serious about it (and quit) - You lose interest or enthusiasm or settle for being mediocre (and quit) - You focus on the short term instead of the long (and quit when the short term gets too hard) - You pick the wrong thing at which to be the best in the world (because you don't have the talent).”
