No pain, no gain.
It's actually not that bad. I spend a lot of time in the field--a lot of it in the real wilderness--and have even developed a very good recipe for rattlesnake. The problem with them is, unless you get a really big, fat one, they are way too bony to bother with.
But they make a nice hatband on the Stetson.
Dirty? You want dirt? Shower with an archaeologist!
I live in the wilderness and spend a lot of time at 12,000+ ft, hauling equipment. You can't do more than a few miles a day with a load at that altitude.
I always tell myself, "No pain, no gain". And after my lab work fizzles I wonder whether there ever will be any gain.
I don't think very many people understand that to be an experimental scientist, you have to be ready to deal with a lot of frustration.
