A post by Kevin Kelly reminded me of some advice from University. I was in the Commerce faculty taking an Accounting major, but we had to take courses in the other disciplines. The second year marketing course that was mandatory was taught by a Professor with a remarkable resemblance to Alfred Hitchcock. The only thing I remember from that course is a quote from some ancient educational video we had to sit through, featuring a strange looking man with a preposterously bad toupee.
The quote was, “we must learn to make our mistakes faster.”
At any rate, the Kevin Kelly post is titled “68 Bits of Unsolicited Advice” and is chock full of goodness.
His site “Cool Tools” is also worth checking out occasionally.
