New Brunswick, New Jersey

I'll be graduating soon and I need to select what courses should I take for the upcoming semester, but I'm not sure what exactly will I need

If I want to become a data analyst, are there any skills I should work on, technical skills I should learn, and/or books I should read to learn more about this field?

I want to major in something that may not be the best when speaking in terms of my personal priorities.

I have always wanted to start my own business. I am currently in high school, but when I get older I would love to work for myself. I love the idea of having my own business, and providing sevice to people with MY own products.

I am going to be an Illustration major at School of Visual arts. I am currently unsure of different careers that I can go into.

Where should I look to find more professional experience in tech as a high school student graduating to major in Computer Science in college?

I want to know what specific details I would need to include to make up a good college essay. For example, would I need to keep it third person or should I try to maintain formality with a first-person point of view?

I think it's to start researching, learn about what you want, and take notes. I'd like to know what other things I should add to this list.
