That said: Don't become *too* invested in one single career field, no matter the career field. Sometimes it just doesn't work out the way you wanted it to; this can happen on either side (you might get your dream job and realize it's missing the "dream" aspect, or you might get some bad luck and not be able to do the job). If you're too wrapped up in a job as the only thing you'd ever be willing to do, either of those can be a huge problem. For instance, I'd love to be a pilot, but have a medical condition that means I cannot pass a flight physical. If I were determined to be a pilot no matter what, then that would be something I wouldn't really be able to recover from; it's important to realize that even if your chosen field doesn't work out for whatever reason, there are still awesome things you can do.
