To Undo the Future

You wake up and find yourself in an unknown, empty space. You learn that you died and have ended up in the afterlife. Your death is strange because most people have done more good or bad in their life, but you have lived life at a perfect 50-50 split between the two. To remedy this, you are sent back to remake some decisions to tip the scale from one side to the other. You see this as a new chance at life, so you try your best to make the choices that will prevent the events that will cause your death. Will you be successful and live a full life, or will your life be cut short again?
