When we first moved in to our house, I would mow the lawn every Sunday. It was some pretty tough work, especially since our frontyard was sort of in a hill. I didn't get paid for it, and I also wouldn't take any breaks. After a month or so of mowing, I kinda got lazy.
I mow grass. Twice a week. I do the front and side lawns, my brother does the back yard and the little strips of grass around my pool.
My yard is quite large, and no, I do not get paid. Ever. That's because it's a routine job, and no reward is required. Unlike most people, I don't need to be bribed to do something that needed to be done in the first place.
I mow three lawns weekly, including my own. Unfortunately, if I were to do them all in a single day, it'd be about three to four hours until I finished. That's not including trimming around the stone steps of my house, or the apple orchard of my neighbor's backyard. Obviously I don't get payed for my own property, but my neighbors pay me for their own convenience, eighty dollars a month from one neighbor, seven dollars an hour of work for the other.
