Time - Not Enough

Just woke up. At 11 am. Half the day is gone.

If I sleep for 8 hours a day,
and when one sleeps, ones dies (Prof Morrie or someone can't remember who said it),
I am alive for 18 hours a day,
which is 2/3 of my live.

If I die at 90,
I would have lived for 60 years.
Factoring in wasting of 23 * 2/3 of my life studying,
I am left with about 60 - 23 * 2/3 years, which is 44 years.
Considering in factors like wasting my time and stoning,
I am left with barely 30 years.

Is that enough?

I will wake up earlier tomorrow.


Each night,
when I go to sleep,
I die.
And the next morning,
when I wake up,
I am reborn.
