How important is your idea? If you can constantly iterate or pivot does the original idea even matter?
The answer is, Yes.
Your original idea is the foundation of your company. Your idea defines where you are headed. If your idea hypothesis is valid, it will minimize the iterations, make your runway longer, and help you have a clear vision. Idea is important.
