Good for you, man. That's some inspiring shit.I did a complete career change at 30. I originally studied Adult Education at Ryerson and then worked in corporate Training & Development in the energy sector. I was making great money, getting great appraisals and was steadily moving up the ladder. It was a salaried job, working about 50hrs week. I did really like the people I was working with and I enjoyed instructional design/facilitation a lot. However, after a while I started not feeling challenged by it and wanting to be outdoors instead of inside a classroom or at a cubicle. It wasn't my passion and I had a decent amount saved in the bank, so it was not too difficult to let it go and try something new. The things I was really wanting to do was work in greenhouses growing plants, working outside while playing in the dirt and ride motorcycles.
I resigned from my corporate job and immediately went back to school for horticulture and got my motorcycle license. I've been working in the landscape field for years now and thoroughly enjoy my work. I started out working for a company doing high-end design/build/maintenance in Rosedale and Forest Hill. That was a good starting point to learn about a lot of different aspects of the industry. Since then I've volunteered a bunch, studied a lot and worked a lot more. Now I teach horticulture at Humber College in the winters, work at the greenhouses/native plant nursery in High Park in the spring and then work as a gardener for the city in the summer/fall while also teaching motorcycle safety in the summer/fall as well. It is exactly where I want to be at this point in my life. I like being able to sweat from the moment I start work to the moment I get home (unfortunately this sometimes happens in the classroom too. I like coming home physically tired and knowing I actually accomplished something tangible. I like being out in the sun and breathing fresh air.
I get 8 weeks off each year, which is when I travel. I also have the ability to work less now than I did before (if I choose), which comes in handy for being able to spend time my lady. I certainly make less money now than if I had stayed in my previous career, but now I'm very happy and before I wasn't. Changing careers is one of the best things I could have ever done for myself.
Enjoy the big leap!
