Career as a travel agent... what's it really like?

I am studying Education at university. In saying that I study education at university, I'm quite undecided as to whether or not teaching is really for me. I love children - I adore them. I love watching them learn and grow, but I am unsure about this career path.

I have been interested in travel agency, and I am putting this out in hope to find someone with experience or simply knowledge on the industry. What's it really like, and is it a worthwhile career? Income isn't a worry - being happy in your job is more important to me!

Thank you very much! x
