You said that you failed after 1 week and got discouraged, well, let me tell you something. I was failing for 12 months without any success, but I never gave up and eventually I succeeded. Internet marketing is not an easy game, you have to work hard to succeed. 1 week is nothing.
First you have to learn how to be patient. Remember, it will take some time until you see the results. You might earn first money in 4 weeks, maybe even only in 4 months, it all depends how successful you are. Never give up, no matter how hard it could get, no matter how many times you fail, never ever give up and eventually you will score. That's a promise.
