As an aspiring entrepreneur and mediocre academic, I couldn’t agree more. It’s not about making the plan flawless in a vacuum, it’s about getting the raw story real-world validation as early as possible so that the story can be altered and refined with input from real users from the earliest days.
Identify a real pain, get a working theory going about the best way to solve that pain, go talk to people that have this pain and get their input on the way you are planning to solve it and the ways they are attempting to solve it today, and get something in their hands quickly to see what they think. In other words, just get going!!!
My favorite quote from this article: “And win or lose, the most valuable lessons you’ll learn will come more from playing the game than from coming up with the best plan.”
