I've started an experiment on myself. I hypothesize that when I'm bored, I become indecisive, and the longer I'm indecisive, the more bored I become, creating a negative feedback loop in my mind that leads to me having tons and tons of interesting activities I COULD do, but then simply choosing not to do them. To overcome this, I made a simple but rigid decision making mechanism: I've written down nearly a hundred activities I could do at any given point in a day, things I've been putting off doing forever now, like games I've been meaning to play, books I've been meaning to read, shows I've been meaning to watch, etc, but simply never bothering to do them and instead waste time doing trivial things because I can't find the correct impetus to get started on any of them or I simply can't choose which one to start first. I wrote these down in a Google Docs spreadsheet listing them from 1 to 100.
Then I take a glass drinking mug, and two D10s (Both numbered from 0-9, one labeled to represent the tens place, and the other the ones place), and throw them in and shake the mug around before letting them settle on a number, which will be a number from either 1 to 100*, which refers to an activity on the list, and I then do it regardless of my interest in it at that moment. The idea is to see if this has any measurable impact on my life.
So far, I'm already enjoying finding that now, albeit through random chance, I can decide on things to do with my time besides waste it refreshing websites and watching pointless youtube videos. Once an activity is completed it's removed from the list, and so far already I've watched the Night on the Taneyamagahara, and completed the old PS2 game The Bouncer, both fortunately not that long to do.
* = a roll of 00/0 counts as 100.
