A high tolerance for agita
From a Wall Street Journal article entitled "Start-Ups on a Shoestring - The tales of three entrepreneurs who launched companies - for less than $150":
"Making a mistake -- or a string of mistakes -- doesn't mean you're a failure; it's part of the learning process," he says. "There's no magic formula for building a business, you just need a willingness to do lots of hard work and a high tolerance for agita."
Agita. Ugh. Not exactly something that I want to want to tolerate.
