Growing Up
Considering the field of social conducts, an individual trajectory would ideally take the form of a cardioid. Heart influx is of this sort so read next after having understood how heart's electrophysiology work. The expension flow, influx embracing as high and as far as possible limited by compacity and required maintenance of the useful structure (os as to go on beating). Trajectory as a front of wave diverges since starting point, reach a maximum front or circle, return, restore and rest for a small while to preserve future. The aim is so to be able to go on beating, that is live.
Things are more complicated. There is irreversibility, locally to expect some, but not very far, back to infancy is no more than regression like in Alheimer's illness. To consider reality, keep life positive: trajectory under zero is not. So this sort of curved trajectory can be a cycloid. Also, we have to consider heterogeneous complexity. Wise development is to take advantage of fundamental physical principles (the part applying to you) as well as imagine emerging properties qualifying your highest minimal complexity (say as live being unit and as a human: satisfaction of your consciousness (something like your happyness).
Now just for a small tip of this trajectory, like a snapshot of it, consider in the olicognograph above the growing up with material and spiritual joint fields, an extension to cover and twist these 2 aspects. Considering confusion of complexity there is a narrow mid-part (gold globe) of intermediate complexity since contrasts are not clear enough there.
Real maximum reach stay intermediate but abstract ideal goals are generally clearer and those shown there are dual, individually some abstract sense of satisfaction (be it happyness) or spiritual and social: to be pleased to live in a good society (since you have no perverse satisfaction).
