The secret to success is "Don't every quit!"You absolutely cannot defeat someone who won't give up.This is not true. Lots of sports teams, just as one example, are defeated even if they don't give up.Persistence is important, but there are other things that are important as well. You must have an effective strategy. If you decide that you want to go to Mars, but you head in the wrong direction, it doesn't matter how long you persist. It just ain't gonna happen.
