Overcards are my bane

I played $3/$6 at Palace last night, and it was four hours of a very slow leak. I think I won a total of five hands, none of which were hands I'd made on the flop. I played overcards to the flop every time I had them, and they never hit. Pocket tens saw a flop of AKQ, it was checked me me in late position, I bet, and everybody called. I was committed at that point, and in spite of not hitting a jack, I couldn't let it go. My one hand of pocket aces lost to two pair. I flopped top/bottom pair and lost to top two pair. My agressive raises in late position with Kxs or Qxs only paid off once, with QsJs, againt an all-in player with 8s2s who started the hand with only $10. AQo hit an ace on the flop, losing to AK. After the first two hours, down to $10, I bought in for another $100. I made it up to $140, then it slowly trickled away like the first $90 did. Like is often the case with me, I need to work on folding big cards after the flop if I don't have top pair, a flush draw, or an open ended straight draw. It's incredibly tough for me to throw away AJo when the flop comes something like T62 rainbow. At least I won all four Happy Days pai gow hands I played yesterday. Nice money, but skill-free winning isn't nearly as satisfying.
