I think the main takeaway point from the book is, that the idea entrepreneur is lacking action. That means to become a real entrepreneur, you have to act on your idea. From several other books (my favorite: the lean startup) i learned, that the first step would be to test whether there is someone you would help with your idea. Who types of persons and how many would act as a money voucher and pay you (would pay you, not actually has to pay you). Most of the time you create a waiting list of some sort for that. When this test gives you the green light it is much simpler to go the next steps and make it (or let it be made), again act upon it step by step to test if each functionality is understood and needed. Let the market decide. And gather as much feedback as you can get.But my question is simple, how do we go from entrepreneur to ideas to entrepreneur ?
This way you won't waste effort for things don't needed. To get this clear: you will make things that won't be needed in the end, but you put only the minimal effort in to find out, and that effort is not wasted.
Having this said, I think you should implement the first few versions yourself, to proof interest. Every now and then you may not be able to progress further with your current skills and have to decide whether it is better to learn the things needed and specialize more in that direction, or if it is better to outsource this thing.
But as in "The One Thing" (also recommended by @MJ DeMarco in one book) you should always concentrate on one thing, that means you should always focus on one the one skill most important skill for the long term game. The rest you should leave as rudimentary as they are (if you can) or you should let take other care of it. The best examples for outsourcing are lawyers needed to check your website. But what you learn and where you advance your skills is up to you.
