Almost any job is easier with the right tools. Pick screws in different sizes, battery powered power drill, light weight power saw, good wood that is hard dried hard as a rock in the sun. I always cry when I get stressed. It really is frustrating to me, but freaks others out. When I was in college I cried every day in a math class and still got a B--almost had a A. The professor was freaked out--told him to calm down, I cry when under stress. Can't seem to find tears for anything else.
Another thought, if you really need help. Call your local high school and ask if they have young teenagers in a building trades program doing service learning. They can usually send you some really good help. That is where I go when I need extra muscle. Some of those "boys" are really good to teach and help. They appreciate someone having some faith in them. Some of those kids have remarkable talent and skills for their age. Might want to try that.
