make money off the internet

i have seen so many "opportunities" to make money off the Internet. a lot of these offers are just scams to make money off you using the Internet. But there is definitely an opportunity to make money off the Internet, in fact you can make money off of anything that you can sell or offer to someone for a fee! The most important thing is to remember, that it is going to take some work, either phisical or mental. something has to be done on your side to produce results; but it seems that some people are hoping to make money without doing their part, if money was made so easily then it would not be as valuable, period.
