Bird did you know how do all that stuff going in or did you figure it out on the way. I am a quick learner but at the same time i dont know much of what im doing in that area.
Well, I grew up watching This Old House with my mom pretty much literally as long as I remember (I can recall watching the original series - not just Bob Villa, the ORIGINAL house they fixed up). I also have an old man and a big brother who are willing to help me out on occasion, and we're always talking about projects and stuff when the family gets together.
With that said - the info is out there. One of the best, most active web forums I've found on ANY topic is the John Bridges forum that's dedicated just to tiling.
I don't do wiring except basic stuff like changing fixtures and outlets. I don't do plumbing. Otherwise, most home repair is pretty straightforward, and most of the stuff you see needing to be done on House Hunters is very basic paint-and-paper stuff; they're rarely looking at houses where major renovation is required.
I should say, though, until five years ago I had NEVER touched a circular saw. Scared s*less of table saws until I bought one a couple years' back. Had never even paid much attention to tiling until a few months ago. I'm not a complete mechanical moron, but I was certainly... well, mechanically-challenged for most of my life.
