Ideas stay weightless until somebody carries one into reality.

An idea costs nothing and therefore weighs nothing. It acquires weight through the work of bringing it into the world, which is the part everyone underestimates and which is where the difference between people actually lies. The scarcity is never in the ideas.

Stop protecting your ideas and start testing one. Pick the one you have held longest and give it a week of real effort. What it becomes will not resemble what it was, and that is the process working.
