What's better?

A question I am pondering: What's better: Stability or the unknown? Continuity or continuous change?

Next year, do I want to be able to walk to work from my house or to live and work in Valencia, Spain? I think I will apply to do both - but what if I got both jobs....which would I choose? There are strong arguments for both.

Yes, this is a personal question. Just thought I'd ask....
