Quitting when ahead is great as long as you quit forever.

If you're not quitting forever, then you're just pausing. Pausing isn't going to do you any good.

Arci explained this much better than me. You can't "quit" for 10 minutes, or a day, or 10 days. That isn't "quitting." It's pausing. "Quitting" means you don't play any more.
