Yes, I have made money online (and you can too!)
It does take "time" and "work" (sorry, there's no "push button" solution, despite what the "Guru's" tell you!)
The key is to find something that you have an interest in, and go for it!
I would suggest that you focus on these areas:
1- Affiliate Progams (Clickbank, Commission Juctions, etc.)
2- Blogs/Websites (build and then monetize with Adsense)
3- Sell your "services" online (pick something you do well, and then advertise it in the classifieds)
I have also spent the past several months testing several online systems for making money. Some of these had great results... and some were worthless! If you'd like to know which programs worked, please send me a private message and I'll give you this free list.
I would suggest that you pick something that you like and then go out and make it happen. "Taking Action" is the key here! Start today, and you'll soon see results!
All the best - John
