To become a better trader, you need to commit to becoming a better trader. Like other things in life, if you are not committed to achieving a goal, you will not achieve it. Your level of commitment will be proportionately reflected in the balance in your trading account.
Committing to becoming a better trader means that you will continually strive to get better at trading. You will set aside time every day to hone your skills and increase your knowledge about trading and the markets in general. You will read books, newsletters and magazines about trading. You will attend trading conferences and take training courses. You will seek out other successful traders to exchange ideas. You will approach trading as a business and not a hobby. (When you engage in a hobby you generally seek entertainment, not profits.) You will do whatever it takes to get better at trading.
