I am a student nurse right now and have a little less than a year to go and all I have to say is I think you should do whatever your heart desires......
As for working as a tech/aide. I think that is a great idea as a stepping stone to nursing. It will definitely get you to appreciate nurses and especially the jobs of the techs in the hospitals. There are too many people that are nurses that are all about saying "That is the techs job"
You will learn valuable skills that will definitely help with your first semester of nursing school. When you can, ask nurses questions. Like what does this medication do, why do you have to hang a saline IV and not the dexrose, anything that comes to your mind.
The thing about nurses is most of them/us you will be a perpetual student. Nurses are always learning new things, keeping up with reading about new technologies and procedures, medications. Healthcare is constantly changing so your job will NOT be boring.
As far as going to school. It is just a phone call away or a car ride. Go down to the college or university that you want to attend and talk to their admissions department. They will help you start you path to nursing. If anything they can answer a lot more questions then anyone could on here
GOOD LUCK and I hope you find what you're looking for
