Classes overwhelming?

I pulled up the classes that one of the colleges makes you take to become a CRNA and they look overwhelming. Did anybody else have this feeling before they went to pursue this field? Keep in mind that I am still not even an RN at this point.

I have been doing research on becoming a CRNA and have read all of the threads here. About a month ago, I read one where it said to just concentrate on becoming an RN and then worry about becoming a CRNA. This is probably the road that I should take, but easier said than done.

This is what I want to do, and the only thing that will stop me will be myself.

I currently work in a hospital but it's business related as opposed to Nursing at this point. (Purchasing). Plus my brother works in Surgery and I can "shadow" a CRNA while I am pursuing getting my degree, so I feel lucky there.

I appreciate this board as it has given me some answers to questions that I had for quite a while, yet couldn't find the answer to.
