they are like Istock connect sales,like 10c sales on SS too...and many other cases.
I'm relatively interested in the price per content,and of course when I see a 10 cent sale I'm always disappointed,but for me the important thing is the total year-by-year earnings,as long as I continue to earn more year after year I continue to work,when it will be that I will earn 30% less than the previous year in the total between all agencies,that will be the moment when I will quit.
for this year I have already reached my target,having already earned more than last year,so next year I will continue.
