I feel it is difficult to make money online.......

Exactly. I got the same feeling as u have. This is nothing but running after your own shadow which u will never catch. Such are the humbug stories and one should not fall into. It is possible to make some sort of money on surveys one can do since they pay good payouts but those good surveys are all meant for the citizens of US,Canada, Britishers and Australians. Some packages of paid surveys are available on the internet on pre-payment condition but how far they are believable one can't say.
