I build in the safety margins, run the analysis, and the design is solid. Then I check it again. And again. I know the numbers hold, but there's an anxious voice that won't let me close the file, sure I've missed something invisible. I'm slowly learning to trust the margins I built instead of checking them raw out of fear.
More people experience this than they realize.
Your designs are sound, but anxiety keeps you over-checking instead of trusting the margins you built.
