You can't be a successful trader without first being a risk taker. Its just doesn't work that way because, every position in the charts or market carries with it a certain degree of risk. It might move a few pips against you at first but could soon rally back up in profit. Mind you, trading is 90% analysis, analysis that could be always wrong and could be very regretful but in that, you gain experience on a lose.
How you take it determines if you'll be back trading or not especially, when the lose is huge. You keep coming back each time you fail and doing as much as you can to avoid previous mistakes is what counts. Get acquinted with a strategy, build up a risk management strategy and you might have a good shot at trading.
