As someone with chronic insomnia, and a busy life, I can say that personally 3-4 hours a sleep a day is something you can live off of, especially with a nap as well. That's considered biphasic sleep. Throughout history there's been many great men to sleep this way or use other polyphasic sleep to deal with their hectic schedules including Bill Clinton, Lord Byron, Winston Churchill, Napoleon and Leonardo di Vinci....the list keeps going. If you're willing to push yourself, sleep is something that can be sacrificed, so long as you're reasonable and listen to your body as well and balance it with a healthy amount of rest now and then.

I respect your attitude, and agree that if you're willing to do anything to be successful, then you'll get there. You may enjoy this article - 21 Ways Rich People Think Differently.
