My brilliant and profound (or is it profane?) husband taught me / teaches me this lesson.
Perhaps others said it first, say maybe Voltaire http://en.wikiquote.org/wiki/Voltaire, but Steve says it better.
On this day, the desire to perfectly summarize the lessons of 2010 has been keeping me from adding perfectly good lessons and get on with 2011, so no more of that! Here we go with another year!
I have purchased the address janeslessonslearned.com and I am on a roll!
Email me your lessons as you learn them and I’ll give you your own day!
Thank you for a year of lessons!
