<prompt> Human: Im an 18 years old artist and I try to sell my art in different mediums digital,paintings,prints. I managed to earn some money but now I want to learn how to be efficient with my money.I need a way to star investing my money. Im aware that Im not going to become a millionaire by investing 500 into something, but I want to get used to the business side, I dont like to ask my parents for money, even though we dont have financial issues.I was thinking to open a t-shirt store because I managed to get a good deal with someone who has a printing machine and if I can make good art maybe I can sell some online. But is anything else I could invest in to slowly turn 0 into 1 ? Doesnt have to be art related.Thank you! First time posting here so excuse me if its not something i should post here  <response>: I would invest that money into getting your brand out there. Business cards, better websiteEtsy store, fees to showcase at art fairs, etc.
