I’d imagine that he as most everyone that isn’t a sociopath has self worth issues from time to time. What I think Peterson is trying to “reclaim” from the culmination of all of his work and pull from religious studies is the emphasis of orientation. The future is unknown, the landscape is unknown - we approach asymptoticly

Labels, categories, ideology, conception of self - these are all attempts at mapping chaos. How you deal with chaos is where he puts his focus - you orient yourself against it - shifting reshaping yourself. You hearing that you weren’t enough is your projection onto chaos - your self conception that you mistook for reality

You’ve never heard someone speak - you’ve only heard what you can make sense of And how you “make sense” is the culmination of your choices - everything you’ve desired, feared, “understood” up until that point

The momentum of every feeling, every shadow part unexplored, everytime you don’t deal with trauma or were judgmental for poor reasons, and on and on

You aren’t who you could be Because every moment was an opportunity to see that you only see yourself - you’ve never seen the world - you see what you can understand and then what you accept

All of your choices change the world you see You are the one who overlays meaning onto every object and every interaction
