Best advice I've ever received

My Grandpa is a quiet unassuming man who has lived his life under the umbrella of diligence, conservatism and hard work. At several points in my life he has offered me little nuggets of advice. Some have been right on and some are probably right, I'm just not willing to admit it yet.
  1. Nothing good ever happens after midnight.
    Not sure I'm buying this one yet.
  2. Spend less than you make.
    Simple but true.
  3. Alcohol Never makes anything better.
    This coming from a man who has never had a drink.
