What Do You Want to Do After Being Reborn?

After being reborn, what would you most want to do? If you had memories of the next few years, or even decades, what would you want most? Would you start from scratch and build a fortune, win back the person you once loved most, or just slap your stupid past self?

I only want to return to the past, before everything is set in stone, and start over. And I never want to run into him again.
