For me, I don't have one particular skill that I'm excellent at, but instead a huge toolset finely honed to figuring things out. I love delving into completely mysterious stuff and make it work. Lots of my skills are centered around IT, but it doesn't limit me. I'm just as happy programming, soldering electronics, rebuilding carburetors, planning a seige, hunting, whatever the task is. When it comes to view, I think Heinlein said it best:

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects. -Robert A. Heinlein
