i would definitely suggest becoming a cna before nursing school. i played around with the idea myself and decided i didn't have time to take the classes before starting school. it was clear, once classes started, to see who had been, or was currently, a cna and who wasn't. the people in my class had an easier time once clinicals started. you might think going in a talking to patients is easy and natural, but it takes practice, no matter who you are. those with cna experience had no problems. that's just one example. but, if the other job works better for you, i think that would give you some needed experience, as well. good luck!
