Hi Caitlin, this is a great question!
The most important thing to consider while choosing a career or job is that it should really excite you. The job should be challenging enough or you will get bored quickly and will be demotivated. If you enjoy doing rigorous activities, then you should take up a job that require rigorous hard work. But it should not be monotonous. There should be something new to learn everyday otherwise you will quickly feel bored. So look for some job that you enjoy doing and there are lots of opportunities for learning something new.
Regardless of the career you choose, you need to continue to acquire and hone your skills to avoid becoming obsolete.
"Choose a job you love, and you will never have to work a day in your life,” Confucius once said
