I used to build the models myself, tuning them late at night until they finally worked. Now I manage the team, and I'm on the hook for models I can only touch through other people. I sit in reviews describing work I'd give anything to be doing with my own hands.
More people experience this than they realize.
You're accountable for the building but can only do it through other people now.
If this sounds familiar, the Library can help you find the bigger picture.
