I added another safety margin today that the schedule didn't want and the budget noticed. I did it because I can't see every way this could fail, and the people it could harm are real even if I'll never meet them. Designing with that humility isn't a burden anymore, it's just the duty of the job.
More people experience this than they realize.
Designing with humility before what you can't see, holding hidden risk as a duty to those it could harm.
If this sounds familiar, the Library can help you find the bigger picture.
