Word! I felt the same way when I started to work fulltime. I felt my creative juices being sucked out of me. Everyday I worked there it just vanished so slowly. I know I'm way more outgoingly creative than half those bastards there and they only look at me weird, so really I'vve dumbed myself down to their level so that I could be understood and not be so weird.
But I do keep myself creative with my guitar but thats as far as my artsy me ever went anyway..
