For me, 2 things stick out the most..

Not paying attention to form and technique.
Not paying attention to the big 3 lifts.

I didn't start benching with any seriousness until just a few years ago. Same with Squats and Deads. If I went to a gym, it was always curls, leg presses, and tricep pushdowns.

Oh, never enough cardio. I still hate it now, but I know if it was something I did with routine, I'd be in much better shape, both cardio and muscle wise.
