Stay sane. Sleep outside.

In 2003, I worked as a volunteer interpretive ranger at Isle Royale National Park & Preserve, Michigan (www.nps.gov/isro). That summer, I hiked a total of 550 miles, setting foot on nearly every mile (165) of trail on the island.
The following summer, 2004, I returned for ten days to assist with moose and wolf research and completed the remaining miles of trail I had not hiked. The feeling of accomplishment and pure joy was beyond words. To have seen and experienced every step of trail on the island... I felt I had graduated and was bound for larger expanses, less traveled and more remote.
The summers of 2005-2007 brought me to Yukon Delta National Wildlife Refuge (Bethel, Alaska), where I volunteered the first two summers and was employed the third summer as a biological technician, assisting with gyrfalcon research in a large, isolated grouping of volcanoes located 40 miles inland from the Bering Sea and the farther inland Kilbuck Mountains; foothills of the Kuskokwim Range. Here, on the delta and amongst the low, extinct volcanoes, I hiked everyday and slept in a tent for up to 75 days at a time, 80 miles from Bethel, and 15 miles from the next closest person, other than the one person I was assisting.
Also in 2006, I had the opportunity to guide backpacking, rock climbing, and canoeing trips in the Boundary Waters Canoe Area Wilderness in northeastern Minnesota for YMCA Camp Menogyn. While leading young teen boys on quests of self-discovery, we spent every night in sleeping bags, either on the shores of Lake Superior, high above inland lakes on cliffs we climbed earlier in the day, or on pristine lakes in the Boundary Waters.
2008 and 2009 found me employed as a backcountry ranger for Yukon-Charley Rivers National Preserve, based out of Eagle, Alaska. Here, I patrolled the Yukon River via motorboat and hiked and floated the surrounding hills and rivers, including the Charley River, a national wild river.
Lately (Fall/Winter 2009/10), I've been delving into extreme conditions camping, where I lay out my -40 degree sleeping bag and rest my eyes in the bite of the Arctic winter air and under the glow of the Aurora Borealis.
Where I'm going with all this is that in the past seven years, I have become very comfortable spending my nights in a sleeping bag. So much so, that I kept track of the number of nights I spent in a sleeping bag in 2008. From mid-April to November, I spent 100 nights either under the stars, in a tent, or in the bed of my truck, all in a sleeping bag. It is where I know the most peaceful rest, through all the wonderful memories I have acquired throughout the years of my adventures from Michigan to Alaska.
I strongly recommend you try it. But, I'll admit, I'm a little biased.
