Dear future me,
I hope that when I become you, I'll be a better person. There is always something about me that needs to be fixed, and I'll always be imperfect. Remember that. I know it's really hard. I know I don't understand how "this time is different". I'm absolutely certain it is. I mean it. So if you can't fix something, I want you know that I will accept it, even if you won't. So don't dwell on those problems and just let me handle them.
Sincerely,
Hopeful.
