Well done by the author for starting something and getting in to the affiliate marketing hustle ("My work is supported by affiliate commissions."). Seems like he can do the same thing to himself (whereby he works less on this project because it seems stable / he can do what is needed in less time like his original job) and scale up / work on another project now. That would be clever then, that's the real thing to admire here I'd say - the self-propelled snowball technique.
