I have a degree in plant biology, having specialized in plant cloning / in vitro propagation. True be it that I can show you how to double the chromosomes in rare orchids, or turn one plant into ten thousand plants in a small lab space, school didn't teach me the core skills I use on a day to day basis in my one-man tree care empire.
I wouldn't trade my education in, even though, ten years removed, I'm still paying back my student loans. If you have a chance to further your education, it is not a bad thing. Plus there's just nothing like college women.
I use very little of my education, but then again, I was not enrolled in a forestry program. Knowing what I know now, that would have been the preferred program of choice. But, I wanted to be a scientist and I guess the point of this story is if you go with your gut feeling and pursue your dream, you'll become a quality tree care professional if that remains your true desire. One point, though; It's probably easier to get your education, then become a tree guy, than to become a tree guy, THEN go after your education. Ya start making good money and you're likely to get involved in this thing called life. College, for the majority, is better done while you're still young. Good luck with the girls, or whatever your preference, but have fun.
