More specifically, I think at the end, money that I got wasn't worth not spent time with family and pursuing different life paths. My friends who were taking it slow has not much of a different life than I do now.

More deep in that topic, Mihály Csíkszentmihályi has a good experiment where they research about what life worths living by asking many participants with different incomes. Result was pretty clear that after some amount of money the life standard has a plateau.

At the end I think this can be considered as an engineering optimisation problem of scarce sources which is limited "time", therefore if I had a second chance I would choose balance more then leaning to one side of family, religion, work triangle.

This book sounds very good. I'll order it.

Have you read the book "Scarcity"? It had a life-altering effect on me. The authors first illustrate the ways in which poor people make terrible economic decisions (spending it all in the first few days of getting a pay check, for example). Then they show how people who are always short of time -- poverty of time -- make similar irrational decisions with their scarce resource, time.

Once you are assured of a certain financial level, one needs to optimise for time.
