any advice for an idiot (me)?

Anyone care to give advice, to a complete idiot (me)?

I'm only new to trading and bought in this morning at $0.09, had a stop at $0.08 and as a result sold out at a loss. I thought people might have started dumping (I was obviously wrong) (and the fact that the share had already risen by 100%+ - I obviously didn't want to lose too much)

Quite shattering when you see it shoot into the $0.11 -$0.12 range.

Maybe share trading isn't for me, because I think I lack the most important thing - BALLS! I don't necessarily have a great deal of capital, that I'm willing to lose, maybe that's the problem and as a result I chicken out when it comes to trading.

Any advice would be appreciated.... How do you hold your nerve?
