Reliability does not feel like anything while you are building it. You said you would cover the shift and you covered it, and that Tuesday leaves your memory immediately. Ten years later those forgettable Tuesdays are the reason somebody puts their own name behind yours. Nobody can manufacture that quickly, which is exactly what makes it worth something.

Be careful with your yes rather than generous with it. Say no to the things you know you will resent, then treat whatever is left as fixed. A short list of kept promises beats a long list of good intentions.
