Oh no here we go. I am boss, you are the boss! You know why?
Because you control the risk and position sizing! Don't mistaken confidence with ego. You are not the boss when you don't know how to be the boss of your capital.
A trader must have a healthy amount of greed to be willing and able to press winning trades and allow to develop into large-scale winners. But you also need fear, a healthy amount of respect for the markets. Fear and Greed.
