I used to love landscaping, but then slowly our boss got to be such a pest, constantly checking up on us, or demanding more than is physically possible. I still love the work.
Also, I don't mind being told what to do, as long as you aren't just going to stand there and watch. Some of the guys I worked with didn't do anything but "oversee" the work being done--that ticks me off, "PICK UP A SHOVEL AND GET TO WORK!"
Lastly, I hated that landscaping didn't pay enough to pioneer, otherwise, I'd probably still be landscaping.
