Earlier quoted context omitted.
I think there are virtual stock markets that you can partake in to see how good you are (although this likely requires investing time which won't directly get paid back if you do well at it.) I wonder if people who do especially well in them can use virtual stock market success as a stepping stone to managing other peoples' money (and getting a cut).
It's well agreed upon that paper trading is nothing like trading with money on the line. It's ALL about psychology.
It's also pretty well agreed on (mainly from scientific studies into the actual results of investors) that this is not only bullcrap, but believing it's true was a major contributing factor in the enormous economic disaster we're all still living through right now. I'd like to say how galling it is to see someone hasn't learnt the basic hubris-based lesson we paid so much for -- except that I really can't express that in words adequately.
