Hobbies
I seek adventures, which is why I hiked the Appalachian Trail after graduating from college, and why I chose to move into UX.
While I would say that hiking is my main hobby, my weird side-hobby is mentally rating the UX of just about anything I encounter. I'll rate elevator buttons, door locks (why would you lock AWAY from the doorframe??), Apple's complete disregard for Gestalt's principle of common region...
Every PD/UX project is its own adventure, requiring you to approach it with curiosity, a flexible attitude, and ability and willingness to problem solve. Working in UX means we learn about different industries, different people and ways of thinking, and we learn about ourselves - just as any good adventure does.
