Since time is the most precious commodity on this earth, invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop. It's obvious that this is the preferred route, but clearly the road less traveled.
Even if your car rarely goes unused long enough to rent it out to a visiting driver, you can still potentially “rent it out” by turning your vehicle into a rolling advertisement. The site freecarmedia.com pairs car owners with advertisers who are looking for mobile billboards. Drivers can earn up to $400 per month by agreeing to have their vehicle wrapped with a vinyl decal (called a car wrap) provided by an advertiser. Generally, your program will last anywhere from 6 to 24 months, and you get paid for following your normal driving routine.
Once you have that problem or need nailed, the next step is to validate that idea and make sure you’ve actually got customers who will pay for it. This means building a minimum viable product, getting objective feedback from real customers, incorporating updates, testing the market for demand, and getting pricing feedback to ensure there’s enough of a margin between your costs and what consumers are willing to pay.
