Keep your expenses low and your options open. The choice is yours, 4 years to gain real-world experience, or 4-6 years of university to enter the workforce, 10 years of work more to pay off the school debt. Be smart, read books and CEO interviews. What you’re doing now is incredible. I would stay on course, intern for a startup and learn all you can about business (not a role/profession) keep researching successful businesses and applying that to your own ideas. By the time you’re 25 all you’ll know about is how to run a successful business.

Create the market before you sell.

Create a simple website that explains the product, collects email to track users who are interested and keep them in the loop while you create the product. You want to be sure you have lots of users who are ready to buy, (not just family and friends). If you had done this and gotten no interest, than the projects probably a dud and doesn’t need to be expanded on, you have no one to sell to. No need to spend $10k. The only loss is the time or money spent on a simple 1 page website. If you do well finding interest, you can use those numbers to help you build more interest among investors who can help you market this more and get a bigger audience for launch.
