Jings, motivation?  Don't motivational speakers get paid lots of dosh?  In the past I've listened to Jackie Stewart, who was very interesting, Annabelle Gouldie, who was very disappointing, and a Mercan snake oil salesman called Luis Tice who made a lot of money out of Scottish Power, getting all the staff put through his "New Age Thinking" course.
I'm not really in that league.  How about "Go on - post a new calendar with a photo taken in nice weather to make us all cheerful and remind us what it's like when the weather isn't shyte"?  Or even, "Please, pretty please"?
