What should I create?

I don't know a whole lot. I got into this as a hobby. I am attracted to the possibility of creating something all my own. The problem is I have zero ideas of what type of site I could create.

I would like to have a project of some sort (doesn't have to be a blog or website) I just want to learn and feel like I have done or made something at the end. Does anyone have any ideas? What type of projects have you taken on?
