Actually, I think I'm in a similar period to the one you describe having been in. Or at least I've recognised that I'm doing things with no purpose, so I'm planning for the future by doing more things with the purpose of having a broader bank of experiences to draw on later in life. For instance, I recently uprooted my life: got rid of the majority of possessions, ended my lease, got out of all my contractual obligations, quit my job - did that one today, actually - and bought a ticket to an island paradise. When I return in a month or so, I don't even know what city I'm going to live in. Unfortunately, the point I'm at in my career restrains me to one country, at least for the next couple of years.
What do you mean by the fundamental structure of your life being constructed during that period? And what sort of ripples?
We can move this to a PM conversation if you'd prefer. I feel I could learn from your experiences.
