I would count camp counseling, starting in high school, as my first job leading to eventually starting a guided tour service as we were accountable for not just leading, but planning activities-with-a-purpose. Shirley Davies, the first camp director I worked under told us that she didn't want to see us without kids with us. I was an education major, so "service" is the name of the game. I taught in public school schools for three years in Colorado & Arizona before moving back to Los Alamos (my hometown) to get married, where I worked for Los Alamos National Laboratory as a part-time Public Liaison, from which I spun myself off to start my own tour business.
While at LANL, Joe Maestas, a personnel representative (now HR), showed us guides what to tell prospective employees, and we could expand out of our experience. Joe wanted people to get a better feel for the area before signing on--most people at LANL are hired from out of the area.
The highlight for me was starting and sustaining my own tour service, complete with using company owned vehicles--no small task for a shy, retiring sort.
Young folks, or anyone, entering the tour guiding service should respect new comers/visitors--be of service, but not be afraid to share your knowledge, as that is why they hired a guide!
Anywhere in New Mexico is my favorite. Every single place has its strengths, people (though sparse in some places); people love our scenery and uniqueness and variety.
I've been in hospitality business for so long that if/when I retire, I'll probably still be "telling people where to go" (my husband's favorite saying).
