Keep in mind that with most of these free services the users are the pawns.

The idea is to frame everything as a controversy, and linkbaits people into discussing it.

The 93% mentioned is far beyond the expectations of most. Prior to the 20th century (at least in the upper class) a child was taught every thing from Greek and Latin to water color painting without regard to 'talent'. Examine the life of Ada Augusta. While there is no doubt that she was talented, her studies were not predicated on that talent. Today most people foreclose on what they might become accomplished at because they say things like 'I can't draw a straight line' or 'whistle a note' or similar such. Again they have no understanding of just how good that 93% level is. I can't teach you to engrave as well as Rembrandt, but I can teach you to engrave as well as the majority of professionals.

For us, at AngelPad, Thomas and Gokul admonished us to tell a compelling story on what iDoneThis could be and why it was the problem that kept us, the founders, up at night.  It started out feeling like sophistry — post-hoc rationalization to please and persuade investors with a plausible argument — but ultimately, it’s simply an exercise in narrative which is by its nature retrospective and reductive. 

Why did we build that thing we did, out of all the things we could have done, and how did our life bring us to that point?  If it was exploitation of a market opportunity, you need to start over.  A vision is about inspiration, not opportunity — and inspiration comes from self-reflection.  Vision, then, is sight looking inward, a process of “connecting the dots” on your past experiences — giving them logic and trajectory, and solidifying that story into a belief in where that can take you.

Understanding what people really want to know—and how that differs from what you want to tell them—is a fundamental tenet of sales.

The lesson: People are happy to pay for things that work well. Never be afraid to put a price on something. If you pour your heart into something and make it great, sell it.

So here's a great way to practice making money: Buy and sell the same thing over and over on Craigslist or eBay.
