There’s a stark difference between someone that finds a problem and complains about it and someone that finds a problem and tries to fix it.
If you’re a complainer, you innately aren’t someone seeking action, risk, and excitement. You’re complacent. To put it more harshly, you’re content being mediocre.
For everyone else, you are the embodiment of an entrepreneur. If you keep repeating this process enough, you’ll either find a big enough problem to make a business out of it, or you’ll stumble on a solution that people will pay for.
