The #1 thing that I learned in high school which has helped me be a more productive worker and human being was TYPING. The ability to type close to 100 words per minute has helped my productivity a heck of alot more than knowing the difference between sine and cosine or the square root of 122,463.
But the most important life lesson from typing - The harder you try not to make errors, the more errors will be made and the slower you will type. Moral of the story - stop thinking and don't be afraid to fail, and you will succeed better-faster. That grasshopper, is The Zen of Typing.
