I am too busy either
a) looking for more things to add to my lists (I also don't organize those lists properly, and because of that I don't know where to start from);
b) wasting my time on useless and meaningless things like playing Tetris or reading random Wikipedia articles;
c) thinking about the things that I want to read/watch/listen to later (e. g., "What if there is a better album and I just haven't found it yet? What if the album I'm going to listen to is primitive, and I am too stupid to realize it? What if somebody will find the music I listen to distasteful? [even though I don't often talk to other people about my music tastes] Maybe I shouldn't listen to music at all, and do something more productive? [and then I end up doing things described in the second point of this list]").
Nice job! What tetris you playing?
