@Colin-
Good point; and while I agree in many ways with you (thus, why we are talking about this publicly online!), but how about the sense that a person who always has something else to offer (holds some education and such back) could not also be seen as a person who strategically shares what is needed when it is needed, rather than may be seen as having nothing else to offer?
Yes, I am playing the role of the advocatus diaboli!
