I personally find combining Ramit's advice in general with MMM's lifestyle/attitude toward saving leads to an unbelievably fulfilling financial perspective. The only thing different is his "why" is to consume more -- substitute your own why and everything he says is suddenly incredibly relevant to you, whether you save 10% or 80% of your income.
He definitely has a lot of very valuable insights on people, maximizing earning potential, and enjoying a more fulfilling life.
