Thank you Fragment & Goldbeetle. Books that both of you have suggested are indeed great but I want books that deal explicitly with the the students or young adults. Well let me elaborate: I am a third year under graduate student and I have loooots of bad habit, which are severely hampering my studies. So what I want is the self help books which explicitly deal with these problems and suggest me the way out. For example there are books like 7 habits that highly effective people have etc. but they should explicitly deal with students/young adults.
Please help me. I am indeed in great trouble.
