At the risk of spinning this off topic, I am reminded of the lesson I learned years ago when I drilled a through hole through the foundation for our low voltage walkway wiring.
I wondered at the efficacy of my brand new shiny Dewalt hammer drill because it was taking me freaking hours to go a few inches through the concrete. After a couple of these tortuous hours, I cursed and looked closely at the drill - and noticed that the direction switch was on "reverse". Attention to detail is important in any endeavor.
