In a bull market, insist on buying spot, covering positions when the market falls back, and lying down and pretending to be dead when the market is losing money. This is called: standing on the side of time and making friends with time.

All the ideas/intentions/expectations of "buying at the lowest point and selling at the highest point" are ~want~ fart~~
