Ideas Are Cheap. Systems Aren't.
The unfair advantage is building things that last.
Ideas are easy to admire because they fit in a sentence. Systems are harder to love because they need maintenance, limits, and a small amount of stubbornness.
A useful system gives good ideas somewhere to survive. It turns a moment of excitement into work that can be repeated, repaired, and improved.
Build the thing that keeps working after the interesting part is over.
