Apply those questions to companies such as Google, Facebook, eBay, Amazon, etc. and you'll reveal the futility of using three simple questions (or a dozen) to judge the value of a startup or an idea. When doing this you have to mentally rewind to the period in time when they were founded and let go of the knowledge you have about the environment as it exists today.
I think there's only one way:
Startup: Build -> Measure -> Adjust -> Iterate.
Failure: Pivot -> Try again.
Attitude: Never give up.
When you succeed, write a really insightful blog post telling everyone how just three questions gave you the formula to create your instant success.
"Never give up" doesn't mean that you stay with a failed idea or business. It means that failure doesn't take you down. You learn from the failure and move on. The vast majority of entrepreneurs fail far more often than succeed.
