Back to school

I have never been much of a student. I always had to really struggle to get by in school. Never a straight A student not by a long shot. But I did ok. Just ok.

So today an offer was made to me. To return to school. I was in a room of professionals in an area I know so much about but felt well, honestly, they were the professionals, I am just a mom. They think differently.
I have a degree in communications. They know this. They think I am wasting it.
So a program is starting at a UNIVERSITY a really good program. I am so nervous. What should I do? Back to school are they crazy?!?!
Work along side these professionals? Crazy? Have a masters degree?
Drive a Mercedes.... or maybe that Jag? Maybe.
