Learning something new every day............

This is how I describe my certification process thus far...I am about 600 flashcards in,two notebooks filled with notes,4 instructional DVD's, several textbooks, and one chapter remains to have flashcards made for it.Needless to say I feel overwhelmed at this point...Sometimes to the point where I am filled with anxiety..I second and third guess myself...I wonder if I should give up and worry if I will find a job...in this economy and countless other thoughts but the fact is that I am passionate about it, I love it,I enjoy it,and I know it...So I try to silence those voices of doubt and frustration as much as possible and keep going...And when I feel like it is never-ending and I will never finish this and see the light at the end of the tunnel and learn allllllllllllll there is to know I remind myself that as long as I continue to learn new information every day then I am on the right track.
