If you have just joined steemit and don't yet know what you are going to post, then......
.....don't post anything! :{)
Take a little time to look at some of the posts that others have already submitted, leave a few thoughtful comments that relate to the post and it's contents and find a few good blogs to follow yourself.
Those that you are genuinely interested in and have enjoyed!
This will help you make some valuable connections in the community and will likely reward you with your first few followers and probably some rewards also for your comments. In the long run, these are the kind of followers you want to have. Ones that are actually going to take an interest in your posts..
Don't be fooled into thinking that the more followers you have the more rewards you will receive.
This is not the case!
Don't let the urge to make your first post overwhelm you!.
If you allow yourself a little time you will soon find that steemit is a place where inspiration abounds and there is a muse around every corner. If you don't know what you want to post right now, you soon will.
Good Things Come To Those Who Wait! :)
That's all the advice I have for now!
