'Inspiration is Dead'

Yours truly has finished reading Sophie's world and after 300 odd pages of philosophy( including juvenile humour), meant for 15 year olds, thinks he has understood all there is in philosophy. Sartre's "Man is condemned to be free" suddenly has started revolving in his head too much.The 'Existentialist' has suddenly awakened and demands answers to vague and what many would call non-existent questions.
But something like this happened after I had read a grahically illustrated book on relativity also. I stared at the distant 'horizon' but it was un'eventful' and nothing 'special' turned up. I read a couple more wiki links and found that physics( more so the popular science part of it), I understood, but Maths tangled me up. The only thing I still do is look wistfully at the Physics books displayed in the British library, every time I go there. So I have sufficient reasons to believe that this current infatuation will die down.This brings me to the question- What inspiration is inspiring enough? or whether any inspiration can be inspiring enough?

I wish I could say things like my uncle brought me Meccano and I liked it so much that I decided to become a mechanical engineer. I really wish I could. But truth be told- Beggars cannot be choosers and often become  mechanical engineers.

Perhaps I am inspired by so many things that I can't get inspired by any one thing ....sort of "condemned to be inspired' I guess.....
P.S- Ironically, inspiration-challenged yours truly, had an email id - inspire-world@yahoo.com , before some pervert decided to hack it.
