Living happily quote

All men, brother Gallio, wish to live happily, but are dull at perceiving exactly what it is that makes life happy: and so far is it from being easy to attain the happiness that the more eagerly a man struggles to reach it the further he departs from it, if he takes the wrong road; for, since this leads in the opposite direction, his very swiftness carries him all the further away. 

On the happy life by Seneca
