I'm not funding an expensive hobby, this is my business.
One of the most difficult things about trading is consistency. Consistency in not just your trading method, but in your state of mind.
If you need a pep-talk or feeling the blues, don't trade.
Think you need to prove the naysayers wrong, don't trade.
Need money desperately to pay bills, don't trade.
Think your an amazing trader and can not lose, don't trade.
