"But can't see a part timer being much of a tree man. just sayin...how dedicated could you be."
Good question
Personally, I think it's a rather naive, stupid question. Dedication is only required to learn a skill set to the level of expertise you decide is adequate for your purposes or goals. A person who is versatile and a quick learner can develop a dozen or more such skill sets in a lifetime, and do all of them at a level well above
layperson or
amateur. If your goal is to be able to work in a dozen different fields, rather than be stuck in the rut of doing the same job for 50 years, then the amount of dedication required would be substantially more than learning that
"Gas goes up, shit goes down, payday is on Friday, I'm a plumber!"
If a guy likes to fix lawnmowers in his garage for extra spending money, and because he likes doing the work, he can easily become an expert at it. I know such a person, and if you're lucky enough to get him to work on your riding mower, he'll do a better job than anyone in a 100-mile radius of me, and he'll do it for cheaper. He happens to be an electrical engineer with several patents under his belt, and worked for a number of years as a consultant for the military-industrial complex... helping them to develop specialized robotic welding techniques for weapons manufacturing. Welding is another of his hobbies. I met him while working as an electronics engineer for one of the companies developing part of the control logic for such a system.
It's a shame to see anyone accused of lacking dedication to their pursuits, based solely on a narrow view of what constitutes "a proper tree man" or whatever goofball yardstick you choose to hold up against your fellow buzzers. I see recreational climbers, hobbyists, production climbers, scientists, weekend warriors and casual observers on here every day... and all of them are contributing to what it means to be dedicated to trees and their care. Some of them even contribute substantially more real, usable, coherent and productive information and techniques than the self-proclaimed greatest tree guys in the world.
No punch line in this one, kids. Decide for yourself who is "just telling the truth" and who is actually distorting the truth.
