Hierarchy of philosophy for individual growth

Hi
Didn’t know exactly how to title the thread.
First the idea, then the question.

I usually hear attributes, toward a certain type of philosophy, projected toward a certain age group. For example theology might be considered good for young children and teens, existentialism for late teens twenty somethings, while more conservative philosophies are geared toward those over forty.

Would you agree that there is a hierarchy of philosophical models individuals tend to follow through the course of a lifetime. Wittgenstein can be broken up into Wittgenstein I and II (As described in the book Wittgenstein’s poker), Sartre, when interviewed in the late 60’s was shocked on being refreshed how radical his free will sentiments were of his earlier writing. Russell has changed his position numerous times on various topics through his near 100 years of life.

I must point out that I’m not stating the obvious fact that people do change their minds, that’s not what interests me, what interests me is the pattern by which the ideas flow for different people. Is there an hierarchy to the characteristics of philosophies that stimulate certain age groups?

Most imploringly, list the philosophical ideologies by age bracket that you believe to be the most plausible for a common life journey. (ex. 14-20/existentialism, 21-32/neoplatonism, 33/44, solipsism)
