Years ago, realising that some of my team needed some Time Managment training I remember asking why one of them hadn't gone with the rest of the team downstairs to attend?
"I'm too busy" he said
I won't tell you how I made him attend, no doubt it has already found its way onto the Office TV show...
He went and it did do him some good too.
Reminds me to post 60 reasons for a closed mind if I can find it in all my stuff!
