I am 51 years old and have 5 children all grown. I have been travel nursing for 3 years now. It is a very fulfilling experience. You don't have to deal with all the politics of working at a permanent spot. You make good money and meet a lot of good friends. I have been to places I never would have got to go to just working in one spot. The down fall is the work is usually tough. Travelers are usually needed because it is busy or it is a tough place to keep full time staff. You don't usually have sick pay or vacation but I make enough money to take off at least 2 weeks between 13 week assignments and 1 month off at Christmas to be with my family. I also do not maintain personal insurance and I has been worrying me lately, that if I have a serious medical problem I won't be able to work or be able to live if I need an extended time off.
If you don't want to quit your permanent job, take a 4 month leave of absence and try it once. You may never stop!!
Good luck.
