p.s. Other people pursue ChE because it pays well (it does, but it is very hard and stressful, so you earn that pay) or because they want job security (my capable ChE friends have hardly any trouble at all finding work, but most stay at one company their entire career).
Although I myself am not a chemical engineer (I studied industry engineering), my mom, brother, sister, two uncle, and several cousins all studied chemical engineering. Many of them did so to go into the oil industry. Most specifically studied petroleum engineering (a subset of chemical). If you do decide to go this path, it's important to understand that the petroleum engineering job market is heavily dependent on the performance of the oil industry. Some years it's going great and there are plenty of jobs, the next there could be a downturn in the industry and people are getting laid off. In general, oil companies do take good care of their engineers when things are going well (at least from what I've seen). Others I've known studied chemical engineering to stand out in their med school application. There's lots of great reason to go into the discipline but it's helpful if you have some idea of where you'd like to end up. I studied Industrial because it felt like I was able to keep my options open a little more than some of the other engineering types. I'd highly recommend engineering, even if you end up pursing something different after college. The problem solving skills you get with this major in college is really helpful in almost every area.
Hope this helps!
