I will teleport myself to those days in other to correct the mistakes I have done.
What a great idea. Although, you know those mistakes you made caused things to happen that actually led you to be who you are in this very moment...Change them in the past and who knows what would happen to the future you. In deed, if you went back and changed the past the future you might be so different that the future you wouldn't want to go back and change the past and then...Would the future you even exist?
Eish! So frustrating!
