Thrill from selling images online

Definitely, my case is not a successful case. But, it is fun to learn little by little at a time.
Firstly, I shoot for what I like. I don't shoot to ensure the images deliver the concepts of potential buyers.
Secondly, I didn't study the demand in DT.
Lastly, I simply shoot too little. Time to polish my gears and shoot with stock photography in mind!

Here is my poor statistic.
As of now, the official sales is 13 with $6.73 revenue. Let's see how much I can achieve in 1 month.
