"People call it luck when you've acted more sensibly then they have." Amy Tan

When we invest or expend money to make a profit, we start from one of two vantages: Confidence or Luck. The first requires effort, competence, and a thorough understanding of what is controllable and what is not controllable and we plan contingencies for those things that are not controllable. The second perspective is the veritable flip a coin. Luck-dependent investment decisions are based on things like past performance, colorful brochures, and influential arguments.
