You can't just sit down and start coding for your $150 or even $70/hr though. Here are some factors I can think of that change the calculation substantially:

- You have to take time and put in effort to find good contracts. Not all work is billable.

- You will probably want to be able to show clients an app you've already created. If you can make that app a $40k earner then you are in great shape.

- You will most likely have to be willing to put up with less fun and less flexible work for clients.

I think the $40k from 3.5 months of work is amazing and would be a no-brainer for a huge number of people. The big downside is the level of risk involved and the difficulty in duplicating that level of success.
