I can't think of anything in particular that I would have changed. No matter how good your hindsight is, there's no guarantee that you'd actually be happier if you were able to modify some part of your previous experience. Things don't work like that. Any retroactive change would almost certainly entail hidden costs and losses in addition to the theoretical advantages and benefits that you think would accrue, and you have no way to know whether the benefit column would trump the loss column.
I have enough good things in my current MA life that I would be very hesitant to risk them if given the chance to modify the past, even based on superior knowledge or understanding relative to what I started with in the MAs.
