way I ever saw a pilot "work harder than others" was a couple of them who constantly pushed weather in the extreme. They were quite successful at it though not without concerning medical crews a fair amount. Management just looked the other way, all the time, until their practices hit them squarely in the face. We're talking 600/1 cross country at night and so on. These guys had no idea how stupid they were. Eventually they were told to get with the program and obey the rules. They then wound up producing the number of flights the rest of us did.
Moral of the story: Do the job according to the rules and leave the ever burning desire to be the number one producing pilot alone, you've a better chance of living through it all.
