Different ages

When I was a young adult, I read from a science fiction book that the meaning of life is 42, which I of course did not believe. But if one thinks of different ages, it might be so. As a kid one learns from one's parents and is inside their picture of the world, which then sets some tasks that one considers important in life and in the world. If one does not have the freedom to choose freely what to study, one continues quite much inside the parents' picture of the world in one's early twenties. In one's thirties one is more independent and can do one's part in important questions, and in one's forties one gets the freedom to do work in ways that one oneself values but it's urgency is still at least to begin with from one's pöd picture of the world, so that maybe in the age of 42 one fullfills those long time goals in life and in teh world.
Likewise other important jobs have their own time, own imput, and after that one ought to change to something else,to take distance to those old tasks, and aging is one way to do that: to identify with somewhat olkder people or to change profession or the like.
Durimng teh last twenty years I have been writing a lot, first of very important subjects in the world, then of other quite important subjects. But there is only a certain amount of things that one person can give, and so one would need a way to let go, to kind of tune to lower input and to change of jobs, instead of keeping the same position as older. Yet one should not ruin the former important input of the same person.
