Career help please?

There is a fine line between an interest and a pion. Something we find to be of interest will only last as long as it takes us to get to know everything about it. Then we are ready to educate ourselves on another topic. Something we have a pion for, you never lose interest in. We always end up going back to it. Jumping from job to job after a couple months does not look good on a resume, even if you were not fired. It shows an employer lack of comittment when they are viewing your resume, and often will be set aside. Stick with one job while you are in school, unless you absolutely have to switch jobs. Find your pion, probably zoology, from the way it sounds... and go for it.
