Let It Fail!
This might sound crazy, but you should want your idea to fail on the first attempt. Why?
Success at the first attempt hurts the results in the long run. This is because failures early in the process uncover weaknesses in our way of thinking.
Don’t fall in love with your idea, let it fail!
It’s the single most efficient way to improve your idea.
A failure is only a failure if you have learned nothing from it. - T.A.Edison
