If you feel like you've got a close call between quitting and persevering, it's likely that quitting is the better choice. - Annie Duke

A necessary part of becoming a better decision-maker is learning from experience. Experience contains the lessons for improving future decisions. Resulting causes you to learn the wrong lessons.

That we make both types of errors, sometimes sticking too long and sometimes giving up too early, shouldn't be that surprising because whether to stick or quit aren't separate decisions. They are one and the same. Whenever you choose to stick, you are, by definition, not quitting. The reverse is true when you choose to quit.

Success does not lie in sticking to things. It lies in picking the right thing to stick to and quitting the rest.
