This problem is driving me batty. I have this 23 year old kid that is as hard a worker as you could ask for, but, he's just not smart enough. If I work him with a group he runs to each task. He gets more done than anyone else because he works so hard and he's never late. The problem is even doing a repetitive task like lawn maintenance he can't seem to remember everything. I have gone as far as make him a check list and he checks things off he didn't do. It's not dishonest its dumb. My system doesn't call for a second person full time as I run 1 man trucks, the only option is to have him work full time with me ( I'm the only full time 2 man crew ) and I to old for that.
