I'm a horticulturist/landscaper. I can sort of switch what I do each season (Golf course technician, Greenhouse related work, Personal landscaping contracts, Florist, etc.) I'm just in the beginnings of trying it all out now to see what part I enjoy most.
And oh yeah, I sell a lot of my pot to adult clients. Not going to say whether that's a fact or not.... maybe I'm lying, definitely not going to say I make more money from that then my real job... but just because I don't say it, doesn't mean it's not true.
It's like being retired at 21. That's why I have so much time to be on this forum and play videogames lately.
