As for me, I leave the old self that I used to hate.
This is good, leaving that person you didn't want to be. It means you developed into the man you wanted to be, did the work and put in the effort to do so. That's ownership and responsibility. Well done.
I think the most important thing about leaving and carrying something in the past is you already get something you can use to make your future flourish even more.
My thoughts exactly.
