I want to start building a instagram account

I want to start building a instagram account. I have no experience in social media, and I do not use instagram(yes, I really don’t as a 17 year old). I don’t know where to start, how to start, how to be consistent. I do want the content to be something about cars. Open to discussion. Wishing to reach $100 per month in the next two months. Maybe this is not realistic, but tell me your thoughts and advises.
