My entire family can wield hammer, saw, wrench and screwdriver with the best of them.
Also I have friends like Byron, Steve, Jim, Dave and Steve T. who also have that knack for building and repairing. Due to my access to these folks I have gleaned quite a bit of know-how. Enough to be proficient and to have confidence in what I can, and more importantly cannot, do.
In my department at work. I have emerged as the defacto fix-it guy. Getting all the Televisions running on the loop, making sure the computers are functional from the various members who have tried out there skills.
Yesterday, I opened and one of the first members to seriously look at the laptops wanted to try out a new Toshiba, laptop. This model had come in during my days off and was not set up correctly. Luckily I was able to find that booting with the 9 key pressed allowed you to restore the system. Good tip..
