Someone once asked me the same question in a job interview. I responded by "I welcome change, I thrive on change. If things don't change what kind of world would we be in?"
Recently, I've basically finished the big construction in my house. I'm very happy to say I have a beautiful kitchen and a great bath. Work is ALWAYS changing, it's never the same thing.
I'm ready for another big change though. I love learning new things and generally a big change occurs for me to have that opportunity.
BTW, Andrea, after scouring my new book I think I've narrowed down your secret but I'll never ask for a confirmation.

Wonderful btw.
