Once, when I was stuck in a blizzard at ORD - it took 36 hours to get home again. I sat next to a pilot deadheading to DEN on the first flight out after the airport resumed operation and he told me something that has helped me to handle IRROPS much better over the years.
He said that it's much better to be down on the ground wishing you were up in the air, than to be up in the air wishing you were down on the ground.
