I've developed an easy to follow method to stop procrastinating in time "black-hole" sites, like social networks, etc... I've observed that the problem in my case is having the possibility of accessing my account at those sites immediately, as soon as I get bored doing any repetitive task at work, or I have an idea about something I could post in a social network, etc... So the easiest way for me to avoid that is to use a long, very-hard-to-remember password there, write it down in a notepad, and never save the login info in the browser. Bonus measure, you could leave the notepad outside home (in the car f.e.)... that way, losing time procastinating requires actually more effort for me than just stand up for a little and then return to work. The point is never allow that to be an easy option, an easy way to escape from responsibilities... Installed "walls" via browser extensions etc never really worked for me, as in the end I just disable them if I feel that's bothering me. PS. Also of course, avoid to save the cookie session once you close the browser in "dangerous" sites...

Memorised a 14 character (incl. punctuation) password after attempting that, and really didn't take me long, unfortunately.

Go for 64 characters then, if possible :-)
