How do you start a business with no money?
I'm a 20-year-old college student studying applied mathematics. I'm back at home for the summer break, and am looking into ways where I can expand my understanding of businesses. I am on a merit-based scholarship, so I've never had to take out a loan. I have a great credit score, and I also get a scholarship refund. However, I have no stable, full-time job since I have been relying on internships and temporary positions. So, apologies for the stupid question, but how does one truly start a business without money? If I were to start one now, wouldn't you need to have a stable, full-time job for at least a few years to be able to pull a low-interest-rate loan? Are loans the only solution? Or do you have to find investors? Where would you even find them?
I know it varies by businesses, but I am curious about the logistics of opening a mini market, gas station, or laundromat. How would inventory work?
