In my experience, there is a missing piece which is this works if your day job and projects use a different part of your brain. Anytime I have had success having a day job and a side project my activities were different enough that they didn't share the same block of mental energy. E.g. once as a waiter working 10h/days and then maintaining a growing website 5h before sleep, another time as a programmer and then doing CAD design in the evenings. You will notice that the author and the personalities she gives as examples also all have this in common to a certain degree. The other thing is I don't think I would think as side projects time investments as a compound interest function just as passive investing. Before you can get there -- and it only applies to some projects, the commonality is attending to your basics like a series of buckets that you have to keep full enough for a long enough period that none deplete to jeopardize your plans. Some projects require a certain amount of momentum or time availability (as do some jobs), so sometimes maxing out your buckets and then going full time to test your idea is a better strategy. Failing is okay as long as you learn enough to make significant progress on the next try. One of these bucket is maintaining meaningful human relations (doesn't have to be significant other), so I wouldn't be taking the author's advise literally.
