You're not the only one here. I've been feeling this since 4-5 years now. This one thing has made achievements senseless to me, and things that others find happiness in, I don't.

Many say that I should do things that gives me satisfaction, or something that gives me a reason to live up to, a goal and something that gives you a sense of achievement.

A few years ago I read this quote on Dignity's Skype profile: "The greatest gift you can give others is the ability to witness your achievements", and since then, I've tried to bring in all the small improvements I can in myself, to give the people around me a reason to be proud and, which gives me some comfort and satisfaction.

Although I still don't feel completely satisfied, but some sort of this feeling is better than nothing.
