I've met more than a few people that have made or are pursuing nursing as a second career. What did you do before? What are the ups and downs in comparison?I'm not a nurse yet, but since I'm the OP, I'll go first. After being a fast food worker, a pizza cook, and a warehouse worker for Best Buy, I was an intel analyst in the Army, serving everywhere from infantry battalions all the way up to division headquarters. Later, I was a targeting analyst for an established defense firm, and later still for a an upstart company that took the contract from my original bosses. 10 years down the road and seven countries later, I'm knocking out the rest of my pre-reqs before I begin nursing school in January.
