Meaningful or living with a good reason... What's most important is to live a meaningful life than to live a life without knowing why.

I have an unquenchable thirst for knowledge. So I just want to spend my whole life in learning.

i fiel very happy in my life because i have a goal and a way to get this goal ^_^ and what i went to have is the bless of my lord and all the love and the happiness in the world ps: realy sorry about my english , i always try to do my best ...lol

First know youself and love yourself.

That's really a complicated question!
