It is about clicking on your affiliate link....but.... I personally feel it's about teaching others to do the same.I have noticed one or two very confused people here in this post,and I sympathise with you.But just remember we have all been there ! Some are still there ! some are still learning,and in fact you never stop learning,cos you can not know everything in NM,the market is too big !
So what do u do ? start at your own pace,learn about the different ways of marketing,then apply that to your own affiliate links.I personally feel that by helping others within my team to succeed,I get far more "job" satisfaction in seing others become successful in NM.If they become successful,then I do too,that way we all win !
