I've never been big into Amazon, but one day a few years ago my friend told me he had just bought $4500 worth of computer equipment for his office on Amazon. I was furious. I could have got a slice of that pie if he had just used my affiliate link!
So, same friend posts on Facebook a few weeks ago that he needs to buy an expensive camera. I tell him to tell me before he does.
One week later, he is ready to buy and asks me for my Amazon affiliate link. Easiest $109.32 commission I ever made!
I know, it's not really repeatable but it just shows you, sometimes you are rewarded for what you do in the most unexpected ways.
Best part? He's buying more expensive equipment later on this summer and I will get another nice and easy commission payment.
So, don't pay attention to the naysayers, and it may not be a great idea to tell everyone what you're doing as they will only want you to fail. But if you have a few close friends who will actually support you, which I do, it can reward you in unexpected ways sometimes!
