Most of the things I write don't take a lot of time and it's just whatever I'm thinking about. I'm not spending hours trying to write the next great article that might earn $20 if I'm really lucky, but more likely to earn less than $5. It's just not worth it.
The crazy part is that the articles I just write without spending a lot of time on do much better than anything else.
All of my articles published in the morning usually do better than any other time, but I think that's when a lot of my audience in the US is more active. It might be different for you since you live in another country.
