working on my preflop leak

Just discovered a new leak in my game that has been costing me a lot of money in the past. This has been something that should have been pretty clear to me in the past as well, but somehow I managed to over look it again. Simply stated, I play way too loosely preflop, especially in the beginning and middle stages of tournaments. My new goal is to identify these trouble spots and hands, analyze the overall situation, and figure out what the best play is. for example if it would make more sense to fold a hand like AQs or AJs to an early position raise if it means risking a healthy stack thaht would be more useful opening pots, stealing blinds, and picking better spots to get my money in.

Recently I just noticed that, most of the times that I do bust out of a tournament, its because I took a gamble to race for all of my chips with a mediocre hand... really got me to thinking.

leak #1 : Overplaying Ax where x is anywhere from a 2 through a Q, and in extreme cases, a King. While these hands are typically strong when opening a pot when you have position, it becomes a whoe other story when you have to play them out of position or facing a raise in front of you. Unless you spike an A or an even better two pair, chances are youll be facing a sticky situation if you face any resistance. I think for alot of us, we forget that A x (2-K) is still a drawing hand, you need to spike one of your hole cards to make it a real hand, so unless you can confidentally put your opponnent on a range of hands where your Ace kicker is bigger than his ace rag, its probably best not to get so aggressive with it and play the hand as best as possible, all depends on the situation.
