Preparing to move up to $20+2s

[skirtus]

I logged 200 $5+.50 SnGs for an 55% ROI. I currently have 180 $10+1 Party SnGs logged for a 40% ROI. These boards have been tremendously helpful. My short handed play has improved dramatically. I can see the improvement over the last 100 SnGs with an ROI of 52%. Im kinda lost as where to start to improve my play. My mistakes are usually so horrible that even I can see them. For example, last night I pushed T4s from the SB into a loose aggressive big stack. We were 5 handed at the 50/100 level and I still had T800 in chips. I had just placed 5 in a row in the money. I get too cocky sometimes and think Im unbeatable.

Can anything be gained by posting stats with only 180 SnGs?

Read some books?

Post more hands?

Just move up and see how it goes?
