if everyone played tight, the only time we'd all make money is AA vs KK vs QQ vs AK.

Play how you want - read SS (or read it again). The variance will be higher if you are gambling more, but as said above can be very profitable.

First 2 months or so I played I was very tight, got sick of the bad beats and quit playing for a month, then I came back to the game and loosened up my style, I've had a lot more fun, shown a bit of profit & I can't wait to get back to the 'table', even after bad beats.

If sitting the table waiting to move in with a big pair and folding 80-90 % of your hands doesn't sound like fun, don't do it. It's NOT the only way to win. But just starting out, it's probably the easiest way.
