Your degree is never a waste. Employers will be able to see that you can study for something and achieve it. Just think about what job you would like to do. Travel agents may not seem to make much money but with commisions etc they can take home a good wage. Which would you prefer.. A job that pays well that you hate.. or a job you enjoy that is less well paid...
I did a degree in Computer Studies and hated my yr in industry and have not used my degree since I left uni. I am much happier than i would have been doing it for a living.
