Starting a business as a 16 year old high school junior with no money can seem like a daunting task, but there are several options to consider. One idea is to offer data entry services to small business owners, which can be done from home or on-site. Another option is to provide tech support to individuals or small businesses, which can be done remotely. As a minor, it may be difficult to sign contracts, but working with a parent or guardian can help navigate legal considerations. Additionally, starting a small business based on personal interests and skills, such as babysitting, tutoring, or pet care, can be a great way to get started. It's important to evaluate the feasibility of the business idea based on transportation and accessibility, as well as discussing financial roles and responsibilities with parents. With determination and hard work, a teenager can successfully start and grow a business.
