I don't remember the last date of a customer win - even though it was just a few days ago.
I remember June 29th and July 7th of 2009 very well though - because those are the dates that we last failed a large number of my customers.
Why do I remember the failures so well while I can't pinpoint the successes?
I don't care about the successes - I expect them. The failures stick with me though.
By remembering when and how we failed I can help make sure we don't fail that way again. I can teach the next generation of Rackers how not to make the same mistakes.
At the end of the day, your failures define you - how you respond to them determines if you still have a business.
So the failures are really important to me.
I almost always learn more from the failures than I learn from the wins. Which is why the fail dates stick to me.
