Do you have any experience in business or business-like activities? If not, you have to invest in yourself first. You cannot earn money wisely if you will not learn before everything else.
I can give you some examples of earning money in the internet, but I think that it isn’t wise work:
get paid to read
clicking at paid ads
and so on.
Learn how to sell and you will earn a lot of money, join network marketing company with good training program.
