Yeah, maybe I should have let go of the old boyfriend who took up so much of my time in high school, or put more into studying and getting into a better school and getting my degree earlier, in a more lucrative field or something I would have been more passionate about. But, if I had, so much of my life that I like NOW wouldn't have come about: DH, the friends I've made from my various jobs and moves, etc. So, those things from way back when, those "mistakes" I wouldn't change.
The things that I WOULD "do over" are:
I'd have taken my dog Gilda to the vet earlier, and maybe saved her from having to be put down for kidney failure.
I'd have done everything in my power to convince my friends to buy the house next door that they were looking at instead of buying a house that ended up being the site of a random robbery that cost them their lives.
And, I wouldn't have taken the job that I got three months ago.
