I've been in internet marketing since 2004. I was finally able to start doing it full time in 2007 and have been successful at it ever since. It takes awhile to learn and even then, nothing is guaranteed that you will succeed. The trick is: don't look for shortcuts.
Wow mate. That's a long time to be in Internet Marketing and not been successful. Well I myself has quit it years ago because its really hard. That's why I say to have to invest a lot of time in it. Yeah, there is no shortcut. Even if you used blackhat method to earn, it is just a matter of time before you are caught. And Internet Marketing is also evolving as well, so you better be updated or else your method will not be successful.
