If you walked into a casino with the idea of playing roulette, you might set yourself a limit. Perhaps you would be willing to risk some small amount. If you lose just a few dollars, it's no big deal, and you have bought yourself a bit of entertainment. But when you raise the stakes and you choose to bet more than you should, it's no longer enjoyable and can be extremely stressful unless you almost always win, which of course is pretty much impossible. We know that the stakes are always stacked in favor of the house. You may be considering a gamble now that is bigger than what you can afford to lose. Start small as a way of assessing your risks, and that will tell you how far you can go.
