Will having cavities make me a bad hygienist?

I have always known I wanted to be a dental hygienist and just recently was accepted into the school of my choice.I have gone to the dentist recently for my 6 month check up and it turns out I have quite a few cavities in my mouth. Especially in my back teeth/old fillings. This may be silly but it makes me feel a little insecure. I feel like I wont make a good hygienist if I can't even prevent my own teeth from tooth decay :(
