Beware of Fake Passive Income Claims

All you see online is how people are making $10,000/month selling T-Shirt, printables, or releasing low-content books.
Be wary of such claims. They may be true, but you seek actual long-term passive income. This income comes from dividends, rents, and royalties.
No matter how you make your money (working a job, driving a taxi, playing an instrument, etc.), you must get cash into your money system (dividend portfolio).
Once you have enough money in dividends to fund your lifestyle, you are truly free. Focus your attention only on those living the passive income life, not hustling and calling it passive income. Good Luck!
