Affiliate Marketing Secrets

Hey, so I am wanting to start a blog, but really have trouble with all the small ones I do start. I can never just think of something to post. I know blogs should pertain to a certain genre or niche, and that they should be something I am enthuisastic about, but there is just so many blogs out there already and I am having trouble picking a topic. So to my question
What draws people to a blog? Just to read the posts? Or is there something more?Why do people jump on the computer and say, Im goign to visit this blog?

I want to be a market affiliate but more or less clueless about it. Moreover, the different sites are just bragging about themselves and less about the real process. So can anyone point me to some good resources related to this topic? also which market affiliate site is genuine , please let me know.

Please help me, I am so confused
Thank you

I’m interested in medieval art, classic literature, and contemporary art while they know nothing about anything on those particular subjects and certainly would never accompany me to an art exhibition or look at my art pieces and give me honest, profound feedback instead of just saying, “oh how nice!” and veer off topic to gossip. We have nothing in common and a lot of the time this upsets me because I’m like a foreign person to them. They misinterpret me on a daily basis and get impatient when I try and talk about art or literature. Most of them don’t even read for leisure purposes. I feel like I’m a different species because they don’t understand me at all and don’t try to…
Is that totally normal? I’m I just being picky and weird? I know there are actually people in my school who share interests with me but I don’t really approach me because none of my friends are affiliated with them and they’re part of a whole different group…
