Sustained and courageous effort enables man to see fate turn its back and flee – Tirukkural

Think well before taking up any work. To start thinking after beginning the work is disgraceful.

Sustained and courageous effort enables man to see fate turn its back and flee from the field.

No one can blame you if nature has not endowed you with superior intelligence; but to have knowledge and to fail to put forth our best effort is blameworthy.

Watch beforehand. He who is not vigilant will repent later in vain.

There is nothing that is impossible if one brings to bear on one’s work the instrument of a vigilant and resourceful mind.
