## How does one learn to cope with technology?

When I leave the 'grid' for vacation — weekend or week-long, it does not matter — I feel liberated. Free. Refreshed. When I return, ubiquitous media (especially television and internet) really get me down. Then, after a few days, I'm back on the grid, sucking from the teat of technology. I feel dirty. And guilty. Still, I love technology. It's like I'm addicted (especially to the internet), and only quitting cold-turkey helps.

**How does one cope with technology? Without becoming a Luddite, how does one break free of the addiction? How does one find balance?**Note that I mean*all*technology — cars and phones and iPods, too — not just television and internet.## Excel spreadsheet question

I have a complicated Excel valuation spreadsheet. The "bottom line" is affected by about 20 variables. I'm comfortable fixing about 17 of them, but for the remaining three, I wish to output to a 4x30 matrix, consisting of parameters A, B, and C, and the bottom line value that corresponds to each of the three. As it stands now, I can plug and chug, but it's a bit unwieldy, and I may wish to make a bigger matrix soon (I'll keep the 4 parameters, but I may wish to go 4x100 or the like).
I can't reverse engineer the entire spreadsheet-- it would take forever. So, how do I build this matrix? [more inside]
