Second chance: Hypnosis

I was 31, laying in a pool of my blood. As my eyes closed and I slowly lost consciousness, I thought about all the wonderful things in life I would miss. My family, friends, pets. Everything I loved would be taken away from me when I died.
With that thought, I died.
However, God, the universe, or whatever it was, brought me back to life.
I was in the past!
This time I will accomplish everything I couldn't in my previous run.
With the power of hypnosis and a second chance, I will etch my name into the history books!
But is it that simple?
How will this power change who I was?
