What if we could relive the past?

I was just thinking like what if we could really relive the past. Like if we could do what we do on computers and just hit the back button and go back and erase it and start over! I know my past is what helped me get this far in life but what if the choices i made in my life didnt happen would my life be worst or better. I guess thats why people believe in resurrection, they just know that they may have messed up in this lifetime but god will resurrect us in a world will no more pain nor outcry would even be discovered. Now is that a world that we want? i pretty much wouldnt mind if i didnt have to cry at all thru life but how could i let the steam or pain i have go but then that when no more pain comes in so i guess that goes hand in hand. It seems like to me i rush things so much and dont realize how much time i have at least hypothetically speaking. I always say i want this and want that but i dont never think that im maybe not ready for that or better yet maybe it came i just didnt realize it. I swear i love my family seems like without them i would be an emotional wreck just for no reason! Its so many things in this world that we all cant put our finger on but like we always say in DUE time it will come and i no trust i hate waiting and its crazy because they say when you want something go out and get it but what if we go and get it its not what we need or better yet we wait for something for so long and it wasnt even what we wanted... its so much to be solved at least to me...
