Advice for building foundation for travel nursing!

First, don't pick an area just because you think that it will bring you more work.
Do something that you love, or at least like.
The more areas that you can work, the more flexible you are, this is what is going to make you the most marketable. However, these skills are not something that you can learn overnight. Each area takes timeto master.
Worry more about learning everything that you can, this will make you the most successful.

Good luck in your career................

I LOVE Med-Surg nursing. Is this a high demand area? Also, is there much demand for LPN's in the travel arena? I'm planning on getting my RN, but was wondering if this is something I could do while I work on it? Thanks!!

You would probably be best talking with some recruiters for different agencies to see what they require and then try to fill in the blanks on your resume.
