You can’t escape the responsibility of tomorrow by evading it today.
What a pleasure life would be to live if everybody would try to do only half of what he expects others to do.
One never notices what has been done; one can only see what remains to be done.
Knowledge of our duties is the most essential part of the philosophy of life. If you escape duty you avoid action. The world demands results.
A sense of duty is useful in work, but offensive in personal relations.
I declare my belief that it is not your duty to do anything that is not to your own interest. Whenever it is unquestionably your duty to do a thing, then it will benefit you to perform that duty.
It is worthy of special remark that when we are not too anxious about happiness and unhappiness, but devote ourselves to the strict and unsparing performance of duty, then happiness comes of itself.
Only aim to do your duty, and mankind will give you credit where you fail.
Duty is the sublimest word in the language; you can never do more than your duty; you shall never wish to do less.
New occasions teach new duties.
