No matter how much you do, you’ll never do enough.
No matter what happens, there is always somebody who knew that it
No matter which direction you start, it’s always against the wind
No matter which way you go, it’s always uphill and against the wind.
No one is listening until you make a mistake.
No problem is so formidable that you can’t just walk away from it.
No real problem has a solution.
No two identical parts are exactly alike.
Nobody notices the big errors.
Nobody notices when things go right.
