“And then what happens?”
Repeat the second question 100 times. Because after every good idea, there are at least 100 steps of iteration, learning, adjustment, innovation and effort.
Starting with the wrong idea is a waste of energy and time.
But not committing to the 100 steps is a waste of a good idea.
We put a lot of pressure on the idea to be perfect because it distracts us from the reality that the hundred steps after the idea are going to make all the difference.
Nearly every venture you can point to is built around an idea that was not original or perfect.
The effort and investment and evolution made the difference.
