I don't think I've ever been bored. It's not that I can't understand the concept; it's the revolting laziness it brings to my mind.
Bored? Do something: Read a book. Count the tiles on the floor. Write a poem. Wash the outside of the your house. Rearrange your sock drawer. Make a chart of the light bulbs in your home, with hours on and the duration of time they lasted. Take a walk. Take a drive. See if you can determine the change in your pocket with your eyes closed. Measure your height. Take a nap. Cut your toenails. Pick your nose. ANYTHING but sitting around bored.
In three minutes of writing, I've occupied a substantial amount of time and I didn't even try.
Bored? Get a life.
