Great points!

Now, I don't think that a hustle must necessarily equal "passive income." It can be a freelancing hustle, or a product hustle, or a SaaS hustle, but there's nothing passive about them.

It takes time to come up with an infoproduct, for example, and you've got to promote it, build your circle of followers, etc. And even if you do everything right, there's a huge amount of chance/luck. Your product might take off, or it might crater (or anywhere in between). Either way it's a lot of work.

Anyways, just my 2c, and good luck with your book!
