Sell Your Services.
Tell People about what you can do (Data Entry or Design or Development or Commenting or directory submission or writing content or consultation or research n development or whatever you are good at. )
Spread words about services by social n mouth.
Catch even smallest job if you got it first. And go.
Keep One Thing in Mind: Reading books, ebooks about how to earn online, is not gonna help you much.
Thanks
