Type 2 Fun

One of my friends from my Archaeology Fieldschool last year told me about something called Type 2 Fun. The idea is that many things are fun, jumping in puddles, playing games, a good conversation, watching a movie, reading a book, etc. All those things you would say while doing "this is fun." Those things are considered Type 1 Fun. Just typical fun things.
But there are other types of things that are Type 2. Meaning they are usually really difficult, daunting, and maybe even depressing while we live through them. They challenge us, test our reserves, and are ultimately very rewarding. During the experience you will probably never say "this is fun" but later when you are telling your story and the pain, cold, and stress is slightly blurred by time then you kind of laugh and say "that was fun."
 For my Type 2 Fun things that I've done is camping and working on an Archaeological dig at 10,000 feet elevation with it snowing for several days in a row, which included shifting through wet pebbles without gloves in below freezing weather (see picture). Walking door to door as a missionary when I was fasting, or the intense missionary schedule. The class History and Theory of Anthropology.
However, even though those things are not often going to make me say "woohoo" having a good attitude is still important, because if my attitude isn't at least decent then I might not finish it, and it might just leave me feeling bitter instead of having that opportunity to say instead, that was Type 2 Fun.
