What do promises really means when it was always broken?

I realised no time is to be lose.
Time's precious, as well as it is important.
But still, i can't put myself into the study mood and treasure every single minute & seconds have.

I saw the reactions of the graduated students receiving the results.
There were tears, smiles and laughter.
The atmosphere were hair standing before that.
I could feel the excitement in them.
How nervous they were, could be express only when you're one of them.

I would be sitting just like them in the hall, after 2 years.
2 years, fast!

I'm having the intention of slacking currently, as in not paying attention class.

People, help me!
*scream*
Okay, i've no idea how to scream.
