People seem to think that I am a very abstract person and can visualize anything without having to see it. Things with which I am very familiar do fall under that category, but when I dip out of my element I have to see it. The amount of information I parse just by looking at something is amazing.
Usually I can solve a problem via a 30 minute phone call or by taking 5 minutes to walk to the place having the problem and fix it. A whopping 15 minutes or less vs. 30 minutes of agony trying to visualie the problem.
