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.
Internet needs more commercial and technically you'd have to get more investments and prepare to accept that you will have it in many years or so. There are also different tactics now than what it was used to be. I for one observed some internet marketing and i cant really say they had good times during the early years. I am just curios for you, on how you started and do you have any site now?
