It's great to have someone take the time to show you the trade. I myself mentored someone. It started as a hobby for me. Then Profesional for 20 years. I could do it all. Sadly the trade pay never increased like a Mechanics had and made me bitter,sore back and knees , no 401K ect:. I changed careers at 42. Morgage and two kids in daycare. I survived. I didn't open my toolbox for 4 years. When I did it was to hobby on my own two cars and I love it as a hobby . Sounds like money isn't an issue for you and I can imagine how rewarding it is for you . Congrats! Now just make sure you take care of yourself and use your PPE. Keep the piscs coming.
