Why can't I win...?

So, after getting KO'd out of a handful of .10 games, I finally made two final tables recently and place 3rd in both. One was in a .10 360 seat SNG for $4, the other in a $1 45 seat SNG for $7.

I have mixed emotions about this-they're decent finishes and Im happy about that. In fact, this is the first time that I've made 2 final tables in a game with 100+ players and the first time Ive ever made 3 FTs all in less than a week. Thats an accomplishment for me, but I have to admit I am pretty disappointed in myself and my final result. Especially in the .10 SNG because I was so close to winning it and a 1st place finish in anything with more than 100+ players has been eluding me for so long. It feels like I let another 1st place win slip through my fingers and Im really frustrated, disappointed, and upset about it.
