1. Try to pick a product in a large market. 2. Look at a few existing products and identify a couple of things that you can do better than the incumbents. 3. See if you can solve those 2-3 problems better than others. 4. Speak to potential users and find 10 people who would be willing to use and pay for your product. I can’t emphasize this enough. 5. Give yourself a timeline on how long do you want to persist with an idea. 6. Rinse and repeat. 7. Stay at it and keep iterating. 8. Good luck!
