That is a good question... Let me think when was the last time I was feel bored... Last year in december.
Honestly, when I start to arrange my time and schedule my day/week, I don't have time to be bored. In the morning when I get up, the first thing I do is preparing my breakfast, then I turn on my PC and before I start to do my work I prepare the tea and coffee. While I am working I prefer to listen some music, because it's help me to keep my focus. After I finish with my job, the next 2 hours I am relaxing with meditation and reading some books. Then I prepare for my dancing/martial arts classes and the next 3 hours I am busy with that...
So, the time after 23:00h is for resting and if I am getting bored while I am resting, then it's time to start my favorite game DOTA 2.
