Thanks PF. The definitions are perfectly clear.

But I want to know how one gets paid to do this...... does he teach it? give lectures? write a column? does he specialize in one field or does he have an opinion on everything?

If he gets paid to give his opinion through one of the above mediums people must want to hear what he has to say. But why? Is his opinion any better then anyone elses? Do people form thier opinion on things based on what he says? How does he form his opinions? does he read tea leaves? go by the stars?

Sorry so many questions!! But I'm interested and Mom always said 'if you want to know, ask'.

Besides there could be a future in this for me.


Hey.... stop laughing. Ya never know.
