Give someone full ownership of one small piece and watch how much more they care about the whole.

Helping with someone else’s project and owning a piece of it feel completely different from the inside. Ownership brings the small obsessions: noticing the details, thinking about it on the walk home, minding whether it is good. A borrowed task produces none of that, however important the task is.

Give one person a genuine piece of what you are doing, boundaries included, and then leave it alone. Resist correcting the parts that are merely not how you would do them. You are trading a little control for a large amount of care.
