You will never be perfect. Neither will your work, your kids, your spouse.
So stop freaking out at every little error. Build systems that reduce errors, yes, but don't allow the fear of errors to draw your vision too far inward. We often use the first error as an excuse to throw up our hands and quit. "I can't be perfect so I shouldn't try". What a waste.
When running down a hill, looking at your feet, trying to place each step will almost guarantee a fall. Keep your head up and pick your path down the hill- your feet will amazingly take care of themselves and find a place to land. Will the Russian judge hate the aesthetics of your run? Yes. So? Your goal was to run down the hill.
