Should i study cisco cnna or License practical nurse LPN?

I was an LPN and retired from a state job after 33 yrs. with a good pension. But, the truth is, it really depends on how much money you have to put into your education, how much available time do you have,how committed are you to a profession and how much money do you want to make when you are done. Only you know the answer to these questions. You will make much more as a Licensed LPN than you will as a CNN or CNA, if we are speaking about the same thing. The more money and time you invest, the more you will make when you are done with your education. A Doctor will make much more than a Registered Nurse, but he has put a lot more time and money in too, so evaluate your resources and time and desire, and go from there.
