What's your tile rack morning ritual?

I'm up early with coffee and a board, and I've been wondering if any of you have a specific way you start your day when you're training—do you draw tiles first thing, or do a word list, or just stare at the rack until something clicks? I used to just shuffle and go, but lately I've been doing a little arithmetic on the tiles before I even look at the board, and it changes how I see the rack.
