The good poker decisions you made to get you deep in the tournament will serve you well at the later stages.
I get in more trouble getting reckless with a decent/big stack late in tourneys than I do being too conservative.
What I learned, with a lot of input from posters here, is that I don't need to get ultra aggressive and use a lot of fancy plays. I don't need to raise every unopened button with J2o.
You really don't have to change gears for the sake of changing gears. If everybody else at the table is tightening up as the final table or the money bubble looms, by all means get more aggressive (again taking into account position and relative stack sizes). But if the table is loose, it's OK to tighten up and not spew chips.
Don't worry about the money bubble or the final table. Just keep making good poker decisions.
