Getting my consciousness back - Questions to Start

I am 24 years old now and was admiring my Hindu culture all my life. I have tried hard to find the reason of my admiration. But my thoughts were my belief till now.

Now I am getting in reality of life. After studying much till now and very much interested in Artificial Intelligence with nanotechnology as you can see I am a technical guy, but unsatisfied with the blurry image of my goal and direction of my beliefs.

Some questions stucking in this condition.

1. What is my satisfaction level?
2. Am I happy while eating, working, playing and other activities?
3. What else I need?
4. Why my mood fluctuates?
5. What can i do for others?
6. How to improve?
7. What I get from my culture and religion?
8. What I am going to pass to my next generation?

These questions are large in number so I wouldn't like to mention here that all the questions anyone having in his/her mind while thinking of their satisfaction level will be listed here. NOW WHAT?

SIMPLE .. I am looking for the solution and I have found some traces from history. Lets get it together. !
