I've been creating content for more than 3 years almost every single day. I learned so many things from that related to the content itself and related to the audiance as well. I would say that's really a fun thing to do. It improve our thinking and make us more aware from the world we live in.
I learned that creating content in fact is easy. We just have to find a topic to talk about. If we have ideas to share, we should just share them. Nothing should stop us from doing so. That's why I like free writing. I don't have to set any rules and I can write about something anytime I want.
I also learned a lot about the audiance. People like to consume exclusive content. That's why it should be original. Coping others doesn't help in this situation. Even if we take something from others, we should always add something related only to us. People will not follow the same thing again and again.
I also realized that we don't have to expect a lot from what we do especially if we are not having that big audiance and if our topics are not that famous. It's not about to be trending, but about sharing the content people really like. But, in case the personal opinion doesn't much a lot with the audiance, that should be shared to make others know your position even if that's not that famous.
I also start to notice the change in myself. I started to notice things I wasn't noticing before. Thinking about things I never thought before. That made me more knowledgeable what lead me to meet more people and that's the awesome part. My communication skills improved a lot and I'm still learning a lot from this.
In fact creating content is really great and even if I was a whale who earn enough from his curation, I would create content anyway just to keep my improvement on.
