Ask a trader what is the most important aspect of trading and far to often they answer "profit".
If all we focus on is profit, then the question is how much is enough? What about the losers? Suddenly we've got greed and fear rather then trading.
What a trader needs to focus on is trading well, a good trade is not defined by profit or loss. It is defined by discipline, discipline to a predetermined set of rules that include; entry, exit and risk.
Profit id a by-product of successful trading. Trade to trade well.
