If you had the ability to go back in time and change anything, What would it be?

Interesting Thought...there are many things that i would love to change but the first and the foremost of them would be studying day and night and even harder to get the seat in the Medical College which i happened to loose just coz i was 3 marks short of usual score... That Hurt me a lot at that time...but if i get a chance i would seriously burn the midnight oil and study e1 harder to get that seat back again.....

I would bring back one of my fast computers back 30 yrs back and mass produce from the prototype

Before I went back I studied how a computer could be put together, how all the stuff works. Than go to 1950 or something like that and "invent" the computer and get rich with someone else his ideas =)

I think I will just watch everything I have done in the past because I might change every thing in my time dimension and might destroy it. I believe the reason why the government stop the project of making time machine is because of this theory people are afraid to ruin the balance of time as we see in the movie there are really great disaster if one dimension is change. well this is only my belief I really love watching movie and sometimes I think they are trying to tell people whats going in our world by this mostly the movies created by Steven-Spielberg did i spell it correctly

I would change some of the senseless decisions I made due to inexperience and youth. If I knew then, what I knew now, my life would be a lot different. Because, after all I don't believe in fate, life is what YOU make it.
