All of you should load a website called yourbrainonporn and read an article called The Great Porn Experiment (search it on Google). The science is pretty solid as far as I can tell and the testimonial evidence, although not exactly the foundation of scientific rigour, is pretty convincing.
The basic concept is about giving up porn and how it can readjust our dopamine levels etc to put us in an ideal state for living an anxiety free life. Try it! I've experimented with no porn and it has led me to having a fair few days of complete confidence and sociability. I've now blocked pornography completely on my laptop and I'm going to try to follow the advice on this link to the word for a few weeks to test it out.
I know Mystery already suggested giving up masturbation in order to become more productive, but I think this article really hammers home the scientific basis for his reasoning and acts as a good source of motivation.
