Is pretty obvious to anybody that's ever had or worked in a business.

The other two are common sense. But that doesn't mean that it isn't good to re-iterate these things every now and then, but if you fell off your chair because of any of those three sentences then you do not have much - or even any - business experience, and likely are not quite ready to make the jump.

There are some much deeper insights in that piece than those:

- I started this business to make an extra $200 so I could spend it on video games without feeling guilty

That's a really good one, it shows you that no matter what goal you have when you start out your business you are not going to be even near it (in a positive or a negative sense) when you're a couple of years down the line. After all, why didn't he stop when he made his goal? Why all the extra work? Clearly we set our goals, then the goal becomes the new 'base', and we set another goal. If I can make $200, how about $400...

Another gem:

- The 'time as debt' view. That's a very interesting way of looking at time, and I think that if it is an original then that alone is a huge contribution to running a small business. It also says in no uncertain terms that if you want to run a small business, any small business, you should learn how to do some minimal automation.

There is lots of other good stuff in there, but those two stand out for me.

One really good thing too, is that in spite of doing this for years, Patrick never quit his job or skimped on it. He waited until the right moment, probably constrained by the $-in-the-bank as well as the amount of money made on a daily basis by the job vs the project.
