DAY
#01
Have done list:
Deleted my Steam accounts (did this quite a while ago but it had little effect on my gaming since most games had their own launcher)
Uninstalled all games (Heroes and Generals, World of Tanks... and the rest)
Deleted my video game acocunts
Configured 'Cold Turkey Blocker' to block distracting websites so that I cannot browse sites mindlessly (although I can still access them, when necessary, using my search engine's built-in proxy)
Bought a used camera and lens (Nikon D5300 for £200, lens was £80)
Set my computer to automatically lock me out after 10pm so that I no longer have late night gaming/browsing sessions
Blocked internet access to my smart TV
Added page loading delays for this site, gmail and some others so that I'm no longer checking them continuously.
