Hmm... First year here, and I think my stress started about the time I asked last year's lead programmer what kinds of work I could be expecting as part of that division of our team, and the first word of his response was "uhm..."
After a long pause, he concluded with, "... stuff." And I knew it was going to be a long year.
Music helps, I listen to an odd mix of stuff from older Linken Park, Foo Fighters, 3 Doors Down, Iron Maiden, Rammstein... Right on up the ladder to In Flames, Lamb of God, Devil Driver, Cradle of Filth, Bleeding Through... The list continues. Every so often I even throw in some classical and never think twice about it.
