That person makes $60K/year from 5hours/month but you can't imitate him. It's not really time = money. He is using some kind of personal/company brand that took years to build. There is value, but it's not in the time he is putting.

Okay. An example: Spend 10 years building knowledge and reputation on some field and become really good at it. Then give a one monthly paid talk at some conferences. That goes $5K/talk. Pretty much achievable. You can even make more, depending on the experience and value you bring.

Nope. Not even close. Anyone on here could write it in two days but they'd all dismiss it because it's too small minded.

That's a great deal of money for most people in a developed country too. Especially for about one week of a full time job per year.

Yeah, I'm skeptical that it's reproducible.

he probably sells E-books on how to do it ;)

Might hold the occasional workshop too.

Step 1: Find problem/customers and figure out how to use google to get them to you

Step 2: Solve problem in a high-quality, maintainable, relatively bug-free way

Step 3: Charge a lot (so you don't need as many customers)

Except to add new features, you can literally watch the money roll in since you've somewhat automated getting the customers. And don't do stupid things like iPhone apps.
