I am probably dumb when it comes to ideas because everytime I think of the "next" big idea, it has already been done.

Would you recommened any other blog posts like the ones written by Jaques or Paul that can enlighten me?

I am not looking for a direct "here's an idea" though, only something that will make me think more about the latest problems. I want to go through the experience of a startup at least once and am willing to put in long hours and am open to learning. Any suggestions?
