If you hyperfocus on what will make you money, you may end up really unhappy down the line. You should focus on what you’re good at, as well as what you enjoy, as well as what you might find a job in. Science writers, for example, are in high demand: most journalists don’t understand science AT ALL, so if you majored in a science discipline and minored in journalism you might carve out a unique career. (in general, science types who are gifted writers can go far) Or you could end up in TV if that’s an unrealized passion–it’s not a bad place to be, either. I say keep yourself open, so generally look at large schools with a lot of options so you can find your way later. More options are better than few. But if you really do like science and you like writing–I would go after both, seriously. There are a lot of dynamic career options you could end up in down the line. Marketing for a scientific company, for example, could be lucrative. You could end up writing textbooks. You could work in science policy.
