The past that has disappeared, no matter how hard you hold on to it, it will be in vain.
However, I have never let go of my past.
Yes, there is no going back. If you can't go back, you won't go back. All experiences are engraved on the body and are unique. There is no way to throw it away and no need to preserve it. It is in my body, connected with my bones and blood, and forms the complete me.
If I can't go back, I won't go back. I have the present.
