The Conversation Between Grit and Quitting

In order to succeed, you're going to have to quit the things that aren't worth pursuing. We should not think of grit as a character flaw; we should think of it as a virtue. And if you stick yourself in something that isn't worth pursuing, what that means is that you're not allowing yourself the other opportunities that you might also pursue. The minute that you determine that the next dollar of your investors money is not worth putting into an idea then they do a disservice to you.
