I have been trading on & off, during the last 4 years. But the desire to trade full time has become stronger & stronger recently. It's not that I have perfected my trading skills but I believe that due to juggling between a full time job, and trading part time in the night, one can't really make any progress in either direction.
Trading, to me, is like learning a new skill. First, you need to understand or learn a methodology. Next, you practice what you've learnt, thru paper trading. After that, you jump into the deep end, by trading "live", with real money. This is where the real journey begins...
To me, greed & fear are your worst enemies...they make, or break a trade.
