I hardly ever peruse meditations but I found this old one worth commenting on.

Moving from business idea to a concrete representation is my focus in this response. At one point books referred to an initial representation as an MVP, Minimum Viable Product. This is a 'scratch build' of your idea. My recommendations when trying to develop something like this are as follows:

• (Done here) Write the idea down. Focus on how it saves users time, money, and/or effort.
• Search online for your proposed solution. Someone may (likely) have already beaten you to it.
• Consider not charging users but rather gathering their data and selling it to third parties. People hate paying for stuff online up front. At least consider the freemium route where at least initially all is free.
• Only after you have completed the previous steps start building your prototype. If you lack coding skills learn HTML and mock up all the forms for the UI. Make diagrams to describe the flow and use cases. Then find some coders and induce them to help you (food, beer, coding parties with pizza).
