What do I see in a future partner...

A friend asked me today what I look in a potential gf.

Well, I replied her that preferably a age gap of not more than 5 yrs. Then she queried why, I replied because of mentality, she then quote me what happens if the gal is 10 years younger but had a much more matured mind; well, that kindda shake me a bit to realize that she's somehow right. I'm looking for a mature individual and age don't really matter that much; although more of the time maturity comes with age.

This incident made me realized the importance of questioning what we want rather than leaving just as it is - with a clear vision will one be able to pursue that ultimate aim.
