The final filter for an idea is whether or not you are passionate about the solution. I recall a number of on-demand laundry start-ups that had a market opportunity but whose founders realized, a few years into the journey, that they didn’t really care about laundry. Just because you see a market need doesn’t mean you’re the one to solve it. If you’re not willing to spend day and night, year after year, solving the problem, then you’re likely to fall short or quit before you figure it out.
