forgive me, but... That response is stereo-typical to what an under-performer has to say - and you know it. I have been in the industry for over 4yrs and spent 2.5 at the institution he speaks of. They are all good, and you have to be good on the phone and a real sales person. The degree will not make any difference. If you use effective ( not affective) conversation, technique and method you will excel. I'm living proof of it, and I have trained many top performers. 6 months to 1.5 years your still learning.
Anyway, if you want real advice, help and training contact me personally.
I'm not afraid to put my name up here; industry people know who I am.
Take care and good luck.
