The pursuit of knowledge…….involves a fair amount of waiting…….you plow through the underbrush as a man chasing the golden goose …..then you hit a wall…..too high to climb so you wait……and wait……..pace and wait……finally you sit down against the wall…..when you awaken…. the wall has been reduced to a mere boundary marker and stepping over you continue on your journey…….such is the pursuit of knowledge……. ttucro
