I once heard that there is a midrash that states in Olam Haba, we start each day as children, then the next quarter we are adolescent, then adult, then old age, so that we can enjoy the goodness of each of those stages of life.
Does anyone know the source of this?
Note: I heard this a long time ago, and I have a vague memory that this might have turned out to be from an untrustworthy source, so apologies if so. I also have a vague memory that I ended up finding it ¯\_(ツ)_/¯ and if so I am curious to learn it inside.
