"The "doing" part of trading is simple. You just pick up the phone and place orders. The "being" part is a bit more subtle. It's like being an athlete. It's commitment and mission. To the committed, a world of support appears. All manner of unforeseen assistance materializes to support and propel the committed to meet grand destiny." - Ed Seykota
