Many speak of obvious reasons but am often reminded of Kevin Bacon's line in "Animal House-as he is being swatted "Sir, may I have another", you actually need to have little or great deal of sadomasochism within you, you are going to lose money. I believe growing up in a country where we just expect to do well with anything we put our minds into, we often believe the "gods" will think us special and playing a few times, we develop unrealistic beliefs this will be easy like playing Pacman.
One who enjoys the process of "work" to overcome what you lack in knowledge, not going to be a weekend or a month or a year but years to decade or more is possible. As child like of "Stunt cars" video, you try making these stunts take a great deal of effort in making them work. You have to be able to take defeat and see it as an "opportunity" of trying again different ways. You learn in pieces.
Don't know how many thousands of times of saying same thing "well backtested method", look at your method as your 12 month baby boy, are you smart enough to save his life before he falls into swimming pool?
You spend hundreds or thousands of hours to make well back tested method and yet you sabotage your rules more often than trade as designed. You have to be smart enough to believe in the process and dumb enough to overcome personal feelings.
So unrealistic beliefs, lack of perseverance, lack of well back tested method and finally being too smart enough to trade it. That's why people lose.
