"What I have learned is from now on I will pull stuff off the table and not get so greedy" Don't feel too bad....Almost every individual investor learns that lesson. It is one that most learn early in their investing career, myself definitely included.
Ben Franlin is attributed with saying, "Experience is a good teacher, but usually very dear in price"
That always applies in the stock market....and exponentially in the penny stock world.
Good Luck
