5 years ago, I threw $50 at the internet on a lark when my father-in-law said he was going to advertise his real estate website on the web. I got back almost $1000. Needless to say, I threw another $50 at it.
At the time, I was waiting on the SEC to sign off on the launch of a new investment vehicle I was going to launch, and the freaking lawyers took almost a year. In the mean time, I ended up starting a company based off that first $50, then took a job as head of a Fortune 500 companies internet marketing, and finally broke off as a super affiliate.
I cant code worth shit, I am not creative, I cannot even write very well (although I have never been accused of being concise) yet I make a damn good living off the internet.

Do it Fucking Now. He could not be more correct. Some way shape or form find a few hundred dollars and take a flyer. If you wait until you think you know everything then you will talk yourself out of some good ideas.
