Ask yourself: Does this appearance (of events) concern the things that are within my own control or those that are not? If it concerns anything outside your control, train yourself not to worry about it.
EpictetusIf you wish to live a life free from sorrow, think of what is going to happen as if it had already happened.
EpictetusIt is not a demonstration of kindness or friendship to the people we care about to join them in indulging in wrongheaded, negative feelings. We do a better service to ourselves and others by remaining detached and avoiding melodramatic reactions.
EpictetusAll human beings seek the happy life, but many confuse the means - for example, wealth and status - with that life itself. This misguided focus on the means to a good life makes people get further from the happy life. The really worthwhile things are the virtuous activities that make up the happy life, not the external means that may seem to produce it.
