How To Earn Money Online

I have been asking this question to myself and I wondered if it is possible. I can read everytime I visit in forums that it is possible. I know some blog owners who earn at least $1,000 a month. How do they do it ? That's what I want to find out. There's always a way, yes I know but how I wish I would know how to do it soon. I'm trying it out and crossing my fingers I would reach those high adsense earning figures. And I wanna share with all of you my journey. Wish me luck! -)
