Bottsky is Good

I have Bottsky to my right in the Dise 30 R, we both have nice stacks, and blinds are 75-150. He limps under the gun (UTG), so im 2nd to act, i choose to limp also, with 77. Of course, a bunch of people come along for the ride, and we're 6 or 7 to the flop of aj7. Gets checked to Bottsky, who bets 350 into the 900 or 1050 pot, i raise him to 1100. I raised, bec. I almost always choose to play my strong hand very fast. Enough of the time when I bet hard, I am bluffing that I need to bet hard when i have good hands too, to keep them honest. Of course, here I did raise, like i normally do, but it wasn't as hard as I would have liked in retrospect. My raise gets everyone to fold back to Bottsky who calls. The turn is an 8, and when he checks, i bet 1500. I feel like a fool writing this, but it is true, I violated my weak is strong principle, and he read right through me. He folds, and says 77? Mistakes are good as long as you learn from them.
