Boredom is really a luxury. Only people who have time, which is the most valuable asset for a human being to have, can be bored.
So, first, realize that having the time to be bored makes you a lucky person. Secondly, begin taking advantage of this time to do things that you really enjoy, that give you excitement. This might take a little practice and thought, and the hard part is that it is totally up to you. No one can tell you what you like to do. Maybe that is the reason so many people are bored, because we are always told what to do. Take control over your own choices and decisions and you will realize that you have the power to decide for yourself what you enjoy. Imagine that! It can be simple things like going for a walk, reading a magazine or a book, calling a friend, watching a favorite show. Or it can be something more deep and meaningful, like writing a book, or volunteering as a big brother, or a big sister.
Remember, being bored is a luxury! That in itself should make you pretty darn excited.
