One thought that has entertained me dearly for the past couple of months is that of, upon death, going to a different timeline.
Of all the infinite possible arrangements of matter in the universe, there are most certainly numerous ones that please me.
I will go to one of my choosing, at the age of 5, keeping all the knowledge and memories that I've acquired in this timeline (minus the emotions attached to them) and I will be able to do it right this time around.
The more I think about it the more it makes sense. How many things in life work out in the first try? Why would life itself be any different? Maybe the reason why I failed so much is because this is my first try; the second run will be way smoother and happier. Believe it!
