From the web site Paul’s Tips…
“In many cases it’s true that you shouldn’t give up too early. But at the same time, it’s a wise person who realizes when their efforts are futile.
The idea that those who keep sailing ahead despite all odds and “damn the torpedoes” are the most successful is a seductive one, and it has a certain element of truth to it. But at the same time, successful people also know when the best path is to quit. It’s simply not true that being a “quitter” is synonymous with being a “loser” in every single case. It’s time that myth was shattered.”
