1. Regular expressions. By far the most useful thing to 10x (or 100x) my productivity in just about everything data related. 2. Standard Windows/MS Office keyboard navigation. Couldn't tell you how many hours I've seen others waste by inefficiently trying to select and/or modify Excel cells or portions of text, especially if they need to scroll. 3. On the same note, "advanced" Word and Excel capabilities - formatting, templating, named regions, etc. 4. Cooking my own food, and rolling my own cigarettes. Thousands and thousands of dollars saved every year, and both healthier than premade (yeah, yeah, smoking is bad no matter what, I know). 5. Speed reading and touch typing. Nuff said. 6. Public speaking, and the associated ability to present information that I'm not familiar with on the fly without fumbling about. 7. General technology - being able to plug in a projector or program a VCR or troubleshoot a printer, etc.
