What to post on steemit?

I have recently joined Steemit with a lot of positivity towards the future but have found myself with one question. Sometimes I get an idea to create an article but I find it hard to consistently create creative, engaging and interesting posts to share with everything because I think my ideas are not creative enough or someone else has already made an amazing post about it. Please tell me how you guys deal with this problem in the comments and I'll be sure to upvote them!
