What's more interesting to me is that the point remains valid even after replacing "money" with "love", "financial worry" with "social anxiety", "workforce" with "family" and "career" with "family", viz:
> Grow up without love and constant social anxiety, without a sense of home / self and few / no friends and start in the family when you're a teenager. You find yourself in "always love [more] to be more secure" and "always look for validation from other that you belong". You become family driven as thats what defines you - and a "community" becomes your self reinforcement and friends.
The question then becomes: why the need to identify in the first place? Why the need to "define" oneself (be it via a career or family)?
I've noticed that many of my late-twenties / early-thirties friends struggle with their current lives, and I think it often is because of what you describe: they spent so much time trying to 'become' that they never really considered or learned how to 'be'.
I struggle with this myself sometimes, too, and I consider learning how to 'be' with what I am now to be one of my biggest challenges and most important skills to practice.
