It will probably take a couple years to build a sustainable, passive income. That is the 1st car I have EVER purchased myself at age 29 (I was broke until then and leased from my parents). But the time committed to affiliate marketing and creating great tutorials and YouTube videos was worth it… I work for myself, there is virtually no limit on how much I can make, my schedule is flexible, and I collect enough passive income to live how I want.
If the answer to each of these questions is a resounding yes, rather than jumping to conclusions immediately, take time to research whether or not others are out there making a sustainable affiliate income from products and content in this niche. In a sense, competition is a good thing here—it'll help you validate your idea and prove that it's worth of building a business around.
