I make about $1k a month absolutely, completely passively from Amazon. I've put in maybe 30 minutes in three years. When I tell people this, they see that passive income is real.

Then I tell them about the years before that, where I spent every second I had making shirt and book designs. I had made a single sale early on and I saw the potential, so I sunk every godforsaken hour I had to spare (I also worked full time) designing and uploading, researching, networking, and pushing. I gambled, grafted, and earned it.

It's absolutely worth the investment, but I only know that now. Back then it was an insane gamble - hundreds of hours of proper work for ?????. I stop telling people about my 'passive' income now because no one wants to ruin the dream of freeeee money.
