SO true! I know I personally can attest that I've lost tens of thousands, risking too much with my none, instead of taking what I knew at the time was the safe trade.
By my count, I've left about 30 thousand dollars on the table by trying to get rich quick. Argh, even conservative ly I could have doubled that money by now. Ah well, live and learn!!!
Ouch. That's what is called your market tuition! :D
