A lot of people guard their ideas, thinking that the idea is the differentiator between success and failure. The idea is just a stepping stone to building something, and the real key lies in making that idea successful through great execution. Turns out even if you have a “weak idea” but execute it extremely well, it will still be worth a lot.
So I say, focus on executing. On actually doing something with the idea (not trying to come up with the most brillant one), and see what happens. You’ll be on step closer to success each time you do this. In fact, what’s rare in the world is not brillant ideas, but people willing to execute on their ideas.
