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.
There are three forces, the only three forces capable of conquering and enslaving forever the conscience of these weak rebels in the interests of their own happiness. They are: the miracle, the mystery and authority.
To be kind, honest and have positive thoughts; to forgive those who harm us and treat everyone as a friend; to help those who are suffering and never to consider ourselves superior to anyone else: even if this advice seems rather simplistic, make the effort of seeing whether by following it you can find greater happiness.
Whatever you fear most has no power - it is your fear that has the power. The thing itself cannot touch you. But if you allow your fear to seep into your mind and overtake your thoughts, it will rob you of your life.
Happiness is essentially perfect; so that the happy man requires in addition the goods of the body, external goods and the gifts of fortune, in order that his activity may not be impeded through lack of them.
