Thank you book

I think it was probably yesterday or last week ( though I cannot at all be certain0 but I saw on TV ( naturally during work hours) there is a publication, possibly a best seller where a lady basically writes her outlook ( not the right term, but my time at the computer is short, so it'll have to do) on life- every single day to find and write down in a little journal things that she is thankful for.
What a wonderful idea, an attitude makeover- not just a mode ani in AM but in PM as well.
So now I realize-among many many things that I'm greatful for, I'm not only greatful for the food at my work and also for the many TVs there! Thanks
