Always look for more...
For instance I started off as a writer for content sites where I was getting next to nothing for my articles. Then I decided to see if I could get more, so I wound up here.
I decided the best way to do the type of writing I like and make more money doing it was by being an amazon affiliate, so I did that and started making some money that way.
After reviewing my amazon stats I found a brand of product that was selling far more than others on my site. So on a whim I started looking for a drop shipping supplier for that product. I didn't find that, but what I did find out was that the manufacturer had an affiliate program that pays 20% minimum on purchases compared to Amazon's 6% that I was normally getting.
Never settle, never sit back and say "I'm done". Always look for ways to maximize what you are earning. Even if you don't find something, you will learn more along the way.
One other tip for newbies like me: there are a lot more affiliate programs out there than Clickbank, Offervault, etc. If you decide you want to sell physical products online, Amazon MIGHT be your best bet but always check to see if there are better programs out there for that same product. Some programs don't offer a great deal more than Amazon, but some offer a LOT more than Amazon.
Here's the thing. The above may seem too good to be true but all I can say is there isn't even 1% hype or BS in the above sentence. This WILL BE YOUR LAST WSO to purchase.
