Shenandoah, TX

I have had trouble for some time going back and forth between career paths and was wondering how others figured it out

Right now, I am a gymnast and I'm interested in some type of sports medicin. I'm considering jobs like athletic trainer, physical therapist, and sports nutritionist.

I am 15 years old, and I am interested in biomedical engineering and research. I'm looking for internship opportunities for research in Houston or Katy area or even online if possible.

Online store business to earn as much money as possible to provide for my family and friends and to become a business man in the future to achieve more in life.

please answer quickly as possible.

I am a freshman in high school, I want to be an orthodontist when I grow up, and I want to know the process.

Thanks

I and a senior in high school and my teachers have not been very helpful in answering this question.

Only means of transport I have is a bike. I live 1 mile into a neighborhood and an additional mile anywhere else. Everywhere doesn't seem to be hiring and online work I have trouble figuring out.
