How to renew my passport
It made me 
"now I can go places! yay! Italy here I come =)"
How I did it: Just went to the police station one day, handed in my old passport, took a picture, signed some papers and that was it. Two days later I got my new passport in the mail :) So easy.
Lessons & tips: use the internet and research if there's anything you need to bring, what the opening hours are etc.
