Training, it never ends

I've spent the past 3 days in a training conference. I've been around for so many years and have done my job for almost as many. It seems I know all there is to know. Then some days I find out that there is still so much to learn. Exciting...and depressing...at the same time. Now I'm going to go to sleep. Maybe I'll retain all my newly acquired training so I can put it to work tomorrow morning. Training, followed by work. My life is so full.
