The greatest performers in any field delay instant gratification in pursuit of their ultimate goal, which is to be the best they can be while pushing through less than comfortable situations.  For me, the hardest work is determining a loss target.  I firmly believe that the very best traders determine where a loss is to be taken before determining where money can be made.  It is difficult to consider how much you are willing to lose before you consider the instant gratification of adding to your bank account.  But it has to be so.  Accept a loss and delay the gratification of instant money for the reward of a lifetime of income.
