When deciding what job we want, should we opt for the one that pays more, or the one that you really want that pays little?
For example, I want to be a forensic scientist, but everyone is telling me that their salaries are too low so I shouldn't become one. So, I was thinking that instead, I could become a lawyer, but I don't feel that I would like it. I still have three years of high school left to decide what I wanna do, but its a question I frequently think about.
Try to remember that it's not about your job, it's about your career. You will likely have many jobs during the course of your career, so try to think about what you want out of your career first, then worry about what job is right for you. For instance, you are interested in being a forensic scientist. What is it about that job that interests you? Is it being a scientist? Is it finding clues? Solving mysteries? Once you can figure that out, you may find that there are lots of jobs out there that could be very fulfilling.
About the salary -- Yes, you should be career focused, but I get that you have to pay the bills at the same time. My opinion is that you should aim to make enough such that you don't think about your salary every day. Try not to think about it in terms of "too little". Figure out how much you actually need to make. Write up a budget that takes into account all the things you'd need to pay for (including savings, if possible). Then you've got your minimum bar for your salary and a real number for what's "too little." As for how much a forensic scientist makes, don't take people's word for it, go do your own research.

There are many things you can do while in high school to find out more about yourself and the types of things that would be good career choices for you: job shadow people who are in the jobs that you are considering, volunteer as often as you can for things that sound fun and/or utilize your talents, talk to family and friends about their work, go to career web sites and read or watch videos on various careers, take career interest surveys, get to know your high school counselor and let him/her get to know you, so much so that when opportunities come along, you might be the one comes to mind to recommend for it. The more he/she knows about you, the more he/she can help you in your career search.
Selecting a profession is important because at times if the salaries are low, you may have to take 2nd job to make ends meet.
It is easy to find out what type of salaries are offered for a different professions. Your high school guidance counselors and your favorite teacher can also assist you to make an informed decision.
Many people switch careers, I have seen an individual who had a degree in History. He was a school teacher who decided to pursue the high-tech (software) industry. He became successful because he was good at driving the point and presenting details succinctly to keep the audience engaged. FYI - his net worth was in 8 figures in 2000. The moral of the story - know your strength and apply them to be successful in life.
I get this question often. One thought is to attempt to discover what you really love to do and what you believe you will be good at doing. Once you determine that, invest yourself in being the best you can at it. You will genrally not have to worry about salary when you are passionate about what you do and very good at it.
