There is a nursing SHORTAGE.
I always tell folks to use this to your ADVANTAGE.
There are very few times in your like that ADVANTAGE is yours for the taking.
Take it....NOW.
Get the Associates. Pass the NCLEX. Get into clinical practice. Make Money. LET YOUR EMPLOYER foot the bill for continued study. Most offer tuition assistance that is NOT linked to contracts, service commitments and such.
You are young at 21.
The sky is the limit.
Education is great and I will always be a lifelong student.
However, experience will give you all the answers that education can not.
Good Luck!
You can do it!
