If you are capable of learning, Its a pity you aren't putting that brain of yours to better use.
My guess is your just trolling.
I guess the chappy who pushes the broom is pushing the broom because he isn't capable of much more. He doesn't believe in a flat earth, he just doesn't understand how a pendulum can detect earths rotation. He also does not understand that if a helicopter hovers, the earth does not pass by below, and how water sticks to a ball. Bless him.
He keeps a good clean floor though.
My job is highly skilled, lots of problem solving, Electrical/electronic circuit design on a massive scale. Ever thought about the control gear that is required for power generation, the cooling, distribution, safety features? Not a job for the weak minded. I guess those books I read every day were useful in helping me understand how to go out onto the floor and actually do the work, and keep the power on.
We all started somewhere, lots of us progress but if at 30 you are still on the broom, then perhaps you just cant learn very much, very quickly.
His artwork is fantastic. He draws war scenes and they are realy very good.
