Focus on solving a specific pain point better than anyone else and you'll win.
It could be a unique approach to a problem, a better/faster/cheaper solution.
I acknowledge that there are many tricks, but the real truth is very simple—make a good product. A good product that can solve problems is often the source of long-term value and intrinsic motivation.
Feature set is key. Focus on providing a narrow but compelling set of features that solves your target customer's pain points 10x better than alternatives. And keep iterating based on user feedback to widen your moat over time. Easier said than done but that's the goal!
