Mine's pretty perf as it is, I can't imagine undoing anything that had happened, what if my while being was different? I'm always like omg what if I was born in Detroit and I was a disgusting leech liberal dyke or something. God help me!
To me, I know the general term "perfect life," couldn't exist to me if someone isn't happy for managing to get a wholer happiness. So, ideally, I find that the perfect life is actually the process in which we can only make things better. The "perfect life," to me is always finding inspiration to continue on creating love to better us as individuals.
