The main reasons I would want to be a CRNA are:

1. Love for in-depth knowledge of physiology and pathology
2. Desire to use intellect to serve people
3. Ability to work autonomously
4. Reaching a very high level of expertise in a particular field

Are these valid reasons? Even though I haven't shadowed a CRNA yet, for some reason I feel that this might be the field for me--based on what I've read here and other places.
