day no. 15,019: every man must do his best with what it is his to do

"Fidelity is a man discharging to the best of his ability that which it is his duty to do."
-- Malcolm Douglas, The Soul of Honor

You can only do what you can do, but you must do what only you can do.

Faithfulness, reliability, and trustworthiness are putting yourself entirely to the employment of your duties.

Every man must do his best with what it is his to do.
