The Meaning of Boredom

How does one define boredom?
Is it the amount of free time you have on your hands?
Or is it because you have nothing better to do with your time?
Or maybe it is just what is happening in your head, that makes you think that you are bored.

Because I think I know a lot of people who would not say that they are bored.
Like busy people who think that 24 hours a day is not enough for them.
Or the people that are starving somewhere else in the world, I think they have no time to think about boredom when they are too busy thinking about how they are going to get their next meal

Yeah, after writing this essay, I kind of feel selfish for thinking about boredom when there are so many people around the world that do not have any time for this.

It is selfish of me because I am currently not working at the moment, and I feel like I am wasting my days away by doing nothing when I could be doing something.
I read books everyday as I am trying to improve my English.
Now, I am forcing myself to write, which I don't really like, but am trying to get used to.

Recently, I found a book on Amazon that teaches you how to write 5000 to 10000 words per day. I did not buy it, but I was thinking of buying it as the price was not too expensive. But I think the cheap pricing was because the book had only 88 pages, which I can finish in a flash. However, the comments by other buyers were quite positive and the author had written other useful writing books as well.

Again, I went off subject.
The conclusion is that I think it is the person's fault whether or not he or she feels bored. Because your actions are controlled by you. Nobody can control what you do with your time. So, you just got to make the best out of it. Mine is currently reading books, but sometimes it can be tiring, staring at words everyday, hiding in my room. I mean, I love reading, don't get me wrong, but It just feels really boring at times. HAHA, see, that word came up again. It is addictive.
