Micro tournament problems

[Rips]

Today I did some modifications on my play. I tried to avoid big pots with marginal hands and I played a lot more aggressive in the late stages. I had a couple of beats, and lost most pairs vs over cards and over cars vs under pair races. I did, however, get my best position yet(60th) in the stars 25kg micro buy-in. The hand I got busted on was just purely stupid play on my side, but I was getting short and had only 18 big blinds left.

It worked better for me, but it can very likely be a big coincidence. Any thoughts on the adjustments? Stupid?
