You trade against the sharpest mind in the ocean-like markets. Mental discipline is an undivided part of trading. Please remember the following points:
Understand you are in the market for the long term, that you want to be a trader in even 20 years from now.
Develop your trading strategy, either technical or fundamental analysis. If "x" happens then "y "is therefore likely to take place. You may need different tools for trading a bull or a bear market.
Develop a money management plan, with the first goal being long term survival. Secondary goal is steady money growth and third goal would be high profits. Successful traders do not concentrate on the profit itself but maintaining successful trades regardless of the earned amount.
Winners feel, think and act different than losers. Look inside yourself, eliminate the illusions and change the way you have been thinking and acting. Changing is hard but could pave the way to becoming a successful trader.
