be sure there's no cheating going on. if you're ever losing to any particular people or at particular places, you just have to exercise prudence and avoid them

and yeah, there are people who aren't made for gambling. some have the nittiness in a small enough dose that they can still function effectively, if not optimally, as poker players (harrington). I see myself in this category. Then there are some who just can't. Just as there are some people who just can't dance or like me I just can't sing
