I'm in the process of becoming a homeowner for the first time and I'm such a perfectionist I'm sure I'm going to screw it up. What do you know now that you wish you had known then? I've been reading Black & Decker books, ...for Dummies books, basically anything how-to I can get my hands on. I consider myself mechanically inclined (I'm great at crafts) but inexperienced. Part of me is excited that I can tinker with stuff but part of me is terrified I'll electrocute myself.
