Another thought just occurred to me. When I was in the 9th grade (just a few years ago...yeah right!), I took a typing class. I HATED it because some of the other people in the class really didn't need to be there. They could type!!! I cried to my mother every night, "I can't do this!! It's just too hard." She patiently told me night after night, "Now, Laurlyn, you know you need stay in the class and learn how to type. Don't worry about everyone else, just do your best."
Well, guess what!?!? I am now an Administrative Assistant and make my living at a keyboard! Where would I be now, if I had just given up because I was intimidated by what others could do in comparison?
Don't give up. Later you will look back at the experience and laugh at yourself for wanting to quit. And you will be glad you didn't.
