Live life exactly the same as it would have been.

If I could go back in time, I will still make all the same choices I already had made in life. This way I would already know the results of these choices and I need not spend time worrying about the results, being anxious about the uncertainties in life. Instead I will have all the time on earth to appreciate every finer aspect of life that we so often neglect or couldn't have afford the time. This would then be my second time in life, not a second chance in life.
