Thanks for the honesty of your answer. I struggle with the reality of creating a wilderness focused career. I'm working through it. In general, I agree that it requires sacrifices that most are not willing to accept. In reality, finding a spouse who is an "earner" is what most people do. Any rich BMWs (Burly Mountain Women) want to apply?
As an alternative option, I live what BPL markets as an "ultralight lifestyle". I hike/travel/live more than I work. And I work for low wages. I save more than I spend when I'm working, and I take most of the year off to travel and hike. A "professional" backpacker is the only job I've had for a decade.
Currently, society's "reality" strikes, not because I am broke. How do I live long term? Genuinely, the only sustainable solution that I see is to continue to live "light weight". I consider focusing on travel, purchasing a "tiny house", truck expenses, health insurance and adding to a retirement plan. At twenty six, that's the most realistic path. Some have talked about the path to becoming professional at backpacking as an analog to becoming famous. I don't think that being a "famous" hiker is something realistic, nor something that I desire. Marketing is shallow. Few people have succeeded, and I don't honestly know how deep that success is. The short list is brief: Ray Jardine, Colin Fletcher, Andrew Skurka, Ryan Jordan,... It's not a path that is realistic for most.
If one simply want to earn while spending time backpacking, the jobs are more numerous. I'm not here to name then, I don't want the competition. See you on the trail!
