Where do I get my blogging ideas.

I am totally not one with ideas circling in my head all the time but more of one who can only work if given an idea. Occasionally I get ideas from discussed topics in class and the news but these are not enough. Therefore, I tend to visit blogs of classmates in order to brainstorm of something to write. Although this may be interpreted as ripping off but I somehow cant get my own ideas. I am only able to write out my opinions on something but unable to think of a topic...My vocab is pathetic as well. Looking at all the "cheem" phrases/words that my classmates use makes me envious in the sense that "I want to do that too". But sometimes I wonder, must we really have good vocab? Isn't the main point just to get our message across? So what is the point of using bombastic words? Nevertheless, I am looking for ways to improve this situation as its indeed boring to see myself repeating the same words time and again. The only way for me to improve this poor vocab of mine is to read more books but I am rather lazy and sometimes more of "cant-be-bothered" to find books. Hence, is there any recommendations of good books to read?
