I think that is the biggest "change" we can make. To be self-aware enough to see when we fall into those old bad habits and react differently than we used to. If you can do that, you've come a long long way. Brace for more turbulence ahead, but if your seat belt is fastened you'll be fine.
Oh, and if there is a loss of cabin pressure and those oxygen masks fall down -- take care of your own before attempting to help the person seated next to you.
