Happiness = Reality / Expectations
That formula can be applied to Forex as well. Keep it real, don't over trade, don't think in terms of dollars, and expect to make wild profits, several times a day.
Think long term, steady consistent growth, in pips and percentage of capital. For example a 10% return on investment per day. Multiply by 10 and you made 100%! That's a trade every other day. Quite achievable considering there are approximately 20 trading days per month.
