Mr. Right..? or Mr. Good enough?

Is there a such thing and are we letting great guys who are just that [Great] get away because we have all of these rules and regulations regarding the "special" person that we let into our lievs. Why are we so willing to settle for Mr. "Tooooootally Absolutely Wrong in Every Way" and not give Mr. "Ok, he's great, but not what I wanted" a chance...? more to come...just at "The Atlanta's Children Shelter" venting
