Apart from publishing a post and earn profit through it, if you cannot come up with a good idea to publish quality content, no need to worry about that you can always purchase other members posts using your community balance. 

If you purchase someone's post, he'll earn community balance which you spent and you'll share part of profit which that lost will generate. You can purchase your own posts as well to keep 100 % profit to yourself.

Just keep in mind that the post you are purchasing falling under the rules and guidelines provided by the admins and that its a good quality content.

Buying post ends here, will post about remaining methods soon.
