Happiness and personal fulfillment are the natural consequences of doing the right thing.

It is not he who reviles or strikes you who insults you, but your opinion that these things are insulting.

Ask yourself, "How are my thoughts, words and deeds affecting my friends, my spouse, my neighbour, my child, my employer, my subordinates, my fellow citizens?"

No great thing is created suddenly.

If we are not stupid or insincere when we say that the good or ill of man lies within his own will, and that all beside is nothing to us, why are we still troubled?

It were no slight attainment could we merely fulfil what the nature of man implies.

Men are disturbed not by the things that happen, but by their opinion of the things that happen.
