It worked for me. I kinda wanted to work on something different, didn't know what though, and found out what when I stopped working on the stuff I didn't want to work on. I believe you've got it exactly backwards. The advice comes from exactly the experience this person describes, and the conditions which you think would make my advice better may actually worsen it. If you know exactly what you want to build, you don't need the open schedule factor, as you can scope it and schedule it around what you're already doing, or timebox the project between school years or between jobs. It's when you don't know what to do next that exploring different options pays off.
