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.
How can you come to know yourself? Never by thinking; always by doing. Try to do your duty, and you’ll know right away what you amount to. And what is your duty? Whatever the day calls for.
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.
There is nothing in the universe that I fear, but that I shall not know all my duty, or shall fail to do it.
Where it is a duty to worship the sun it is pretty sure to be a crime to examine the laws of heat.
Who escapes a duty, avoids a gain.
