Yesterday is history, Tomorrow is a mystery,But Today is a gift, That's why it is called "present".

This is perfect sentences…

In your opinion?

perfect:-D !! :)

I like this one:today we're in the changing world,but tomorrow we're changing the world!

We do nothing for yesterday and we don't know date of death.  we realize the worth of today. Because we have only today…

it's the matter of life,and our attitude to the world,but i prefer to face up to the destiny, defeat it!

yeah it like this

live ur day don't think about tomorrow

today is a gift that we mustn't miss.

goods left on our hand only today, not yesterday not tomorrow…

Seize the day~

We always don't know what's happen tomorrow….

In a class, a teacher told us: We can't  foreknow Tomorrow & Accident which one arrived in….. 

it's absolutely right ^^

yess
