1. You shouldn’t sell a problem people don’t have.
2. If your market is crowded, you must find a way to make your product stand out, even if it is simple.
3. Product is the leading side of marketing.
4. Before you create a product, identify the options people currently use to solve the problem.
5. If existing options are sufficient, avoid creating it.
6. If tinkering with the product could make their job easier at the same price point, create it anyways.
7. The most important thing is: Don’t wait. Even a crappy version at the beginning is enough to get real-world feedback.
8. Only paying customers validate your product in the market. Forget free plans, but add a free tier if necessary.
