Great post by Hunter Walk, who is leaving his job after a decade at Google:
Careers are sets of decisions where you have the chance to emerge from the chrysalis every so often and show the world, show yourself, how you’ve evolved. You are not your org chart, your department budget, or your title. Don’t let success at a company prevent you from pursuing scary and wonderful new opportunities to build. It took me a little longer than it should have, but from the other side, it’s pretty awesome.
It’s easy to get comfortable in our org charts, but stepping outside of those responsibilities is when we have the opportunity to do great work and try something new.
