First Rails app complete. Where to Next?

So this is the app I made in order to begin learning rails (and programming in general): www.cachette.ca. You will notice that it's basically a series of rails casts and various tutorials mashed together. The reason I'm posting it on here is to get some feed back and to ask where I should go from here. Please be constructive and feel free to point out anything noobish I've done!

I find I'm getting better at reading other people's code and mashing open source and tutorial code together while altering it slightly to fit my needs. I would really like to get to the point where I feel comfortable writing my own stuff from scratch. There's lots of things I would love to create but don't possess the programming knowledge(yet) to make them reality.

When did you get to the point where you feel like you can create anything you are able to dream up and how/when did you get there?

Based on the quality (or lack of) of my app do you think a web development firm would hire me as an intern? Is this a good route to go?

I really enjoy programming in Ruby and would like to shoot for a job as a ruby/rails developer some day.
