Which is more important to you and why: flexibility or expandability?

Flexibility.

Sometimes some things aren't worthy of expansion - like a bigger family or more wives. Personally I'm not opposed to more wives but I think it's against the law in many places.
Whereas Flexibility keeps you nimble and less likely to break something...like your business, profession or a body part.
