My fourth place problem
 

I have a problem with fourth place finishes. While they are not the most finishes that I have at the moment. I feel as though I should dam the river before it overflows.

Going into the final four my problem is, I believe, that I become too aggressive UTG or UTG+1. Should I be waiting for another player to bust and not take too many risks with playing hands in early position? I make blind steals where necessary, as they are critical to winning a SNG.

People with more experience and expertise, I would like to know what you do during these situations. I am not looking for a quick fix, as I have much to learn about playing SNG's when it becomes five to four handed. The ideal benefit of this will be to maximize my ROI percentage.
