When my parrot passed away at my age of five my mother told me, "She is sleeping."
I think it sounds better if you say something like, '"My parrot passed away when I was five years old, however mother told me that she was only sleeping."
So I believed the somehow connection between sleeping and death, therefore the waking...must be renascence!
"From then on I related sleep with death, and similarly, waking up with rebirth." Something like that sounds smoother (keep renascence if you like it!).
give it a new meaning, like Mr. Jobs said "thinking today as last day of life".
Comma needed.
the essence of everything worthy of fighting for
I'd add "for" at the end of this sentence.
like singing in a springy tone while concerning on serious issues.
You don't need this word.
Hopefully this helps a bit. I like the message you are putting across, very positive! Which country do you come from?
