So nothing is ever good or bad unless you think it so, and vice versa. All luck is good luck to the man who bears it with equanimity.
Nothing is miserable unless you think it so.
And no renown can render you well-known: For if you think that fame can lengthen life By mortal famousness immortalized, The day will come that takes your fame as well, And there a second death for you awaits.
Nothing is miserable unless you think it so; and on the other hand, nothing brings happiness unless you are content with it.
