Let us not worry -Omar Khayyam

Literal:
O friend, for the morrow let us not worry
This moment we have now, let us not hurry
When our time comes, we shall not tarry
With seven thousand-year-olds, our burden carry.

Meaning:
O hark, let us not think of the morrow
Cherish this moment, far from sorrow
Life is a temporal gift that we borrow
Whether dead for ages, or leave tomorrow.

Literal:
In childhood we strove to go to school,
Our turn to teach, joyous as a rule
The end of the story is sad and cruel
From dust we came, and gone with winds cool.

Meaning:
Pursuing knowledge in childhood we rise
Until we become masterful and wise
But if we look through the disguise
We see the ties of worldly lies.
