> it can make a lot of sense to sacrifice one's own happiness to gain more happiness for others. If what you're doing would potentially create more "happiness," or "positive outcome" for others. But most of what most of anyone does has no significant or lasting impact. "Merely satisfactory" gets the truck to the dock on time, the Uber customer picked up and delivered, or the HN post replied to. Aiming at excellence is great, but in most cases pushing toward excellence at all personal cost, successful or not, doesn't really move the needle. Take care of yourself first, unless you're an extraordinary individual in extraordinary circumstances. Most of "this" just doesn't matter.
