The happy man . . . will be always or at least most often employed in doing and contemplating the things that are in conformity with virtue. And he will bear changes of fortunes most nobly, and with perfect propriety in every way.
When we feel happy and peaceful, our happiness and peace radiates around us, and others can enjoy it as well. This is called 'the enjoyment of others of our body of bliss'.
We communicate happiness to others not often by great acts of devotion and self-sacrifice, but by the absence of fault-finding and censure, by being ready to sympathize with their notions and feelings, instead of forcing them to sympathize with ours.
making a decision was only the beginning of things. When someone makes a decision, he is really diving into a strong current that will carry him to places he had never dreamed of when he first made the decision.
It is in everybody's interest to seek those [actions] that lead to happiness and avoid those which lead to suffering. And because our interests are inextricably linked, we are compelled to accept ethics as the indispensable interface between my desire to be happy and yours.
