The phrase 'mastering the market' is just a way to deceive people into thinking they can control the market. Once retail investors have this perception, it becomes easy for big players to actually control the market. The concept of 'mastering the market' has never been something retail investors should consider; only those who can operate in the market can truly master it. There's nothing more to say; if you want to master the market, wait until you become the largest player before considering it.
