Go Back In Time

once in a very random night, someone retweeted a tweet "i wish i could just go back in time and change some things" okay, so at first I thought "wow, that would be amazing" but the more I think about it the more I realize if I really could go back in time an change some things (with an 's' which means I could change not just one thing) the past wouldn't be able to "shape" me onto the way I am right now, things might be so much different, but better? I don't know, apparently not.
If I changed some things in the past, I might have the possibility not to learn something from the past and makes me wiser from day to day. I know I can't say that I am wise enough but at least I acknowledge myself to be better, to be wiser in life. All mistake I made in the past could be the most precious experience and teacher for the future. I myself feel like the stage of letting go the past, accept the present, and prepare the future is a very good combination.
and the thing about wouldn't be able to time travel is the we gotta accept the way we are right now, maybe who we are right now is not something that we can easily be proud of but we can't also just stop in silence. We somehow have to move forward even it's just a little step and don't stop and at some point without we even realize it gets better. People change, so do I, and so does the universe.
