You should be definitely winning on all blind levels. That's how good players are and this your goal, I think
Uhm...Don't go super crazy. Pay attention and add a few more hands into your shoving range when blinds are about to increase. F.e. a marginal push will become a push if I know that next hand I will be down from 10 to 5bb. A close fold will become a close push in this situation.
Try improving your push/fold in general, but don't feel desperate to accumulate chips and do stupid loose call/pushes when you are deep just because 2 blind levels from now- you will be very short. I also notice that most regs are good with their shoving ranges, but they have huge leaks with their 8-5bb eff. calling ranges.
Also, don't make the mistake imo that most regs do when they go 5-6bb short. They start shoving clearly bad hands in order to save FE. I think that minus EV pushes are somehow overrated...or maybe that's not the right word. They are just believed to be a must and people go nuts shoving Q5s, A2o, 85s 7-handed UTG for 5bb, when most of the table is 4-7bb deep. Pay attention to antes. A lot of regs don't adjust properly and antes really do change much.
Watch the vid, post hands and I think this will be a good help for you.
