Everytime you choose to write on a new topic, you need to "Start a New Hub" and then go through the different steps to create it and post it.
As far as writing everyday is concerned, you do not have to stick to any particular topic or guidelines, simply choose a topic that you have a lot of knowledge about and write. Tomorrow you might decide to change to a new topic who knows.
If you thought you wrote a hub, maybe you did but didn't publish it. Look under "my account" and see if there are any hubs in there. If not, then you didn't write one.
If one is there, click edit and then click the Publish button and your hub will be published. Good luck :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
