How do I get a job that pays you a lot of money like an out side job

I am an climbing arborist outside of my normal 9-5. I love the fact that I get to work outside and help people understand how to care properly for their trees. I typically climb the trees to remove, prune, or assess the risk. It is a rewarding job that pays well, but can be very dangerous. If interested in this type of work a degree in forestry is a great start while looking to work as a ground crew for a local tree service. Safety is key and if that is not at the front of the line for the company, I would find another one. There are some great vids on you tube of this type of work. type in arborist and you will find many. August Hunicke and Blair Glenn are one of my favorites and often they discuss what that life is like. Best wishes.
