I see only people who are famous here and they post nothing just like they post a picture of flower and they get so much support and vote

Don't take your cue from these users. They are bought votes. You have delegated a lot of SP for this.

You should not make the posts for the curators, but for yourself and your readers! If your posts are liked by many users and you interact with them, you will get more out of it in the long run than from a vote by a steem curator!
Steem on!
