Good thread NoOne. Who likes being bored? Me, personally, I like doing crossword puzzles. There is not a second of my life I am not involved in something whether it be menial, creative or familiar. It is a balance of all three I think. It can be compared to the experience from taking a trip to a new destination vs the lack luster ho hum of the return trip home unless of course you take a different route home, which is "less boring". I also think it has something to do with the knowledge one has and the "speed" in which they travel mentally through life. Such as being adept at many things yet not having the patience to settle on one thing in particular. Zig Ziglar called it being "cooked in the squat of complacency". In it's more serious stages, I think, is what "depression" is all about. I also think it has a lot to do with gifted young people who go over the wall in attacking boredom with hyperactivity such as can be defined in ADHD disorders. I think I am one of the lucky ones. I have always found ways to occupy my time both mentally and physically (I wish more physically, Ha), but I think it has something to do with staying "busy" but not overdoing it such as what might happen when one takes a stimulus and the "downs" that can follow those "highs".
These are my thoughts from my personal perspective. I hope others will help in addressing what they do to ward off boredom. I think it's a bigger problem than we think it is.
