Robert Louis Stevenson said this quote

To be honest, to be kind - to earn a little and to spend a little less, to make upon the whole a family happier for his presence, to renounce when that shall be necessary and not be embittered, to keep a few friends but these without capitulation - above all, on the same grim condition, to keep friends with himself - here is a task for all that a man has of fortitude and delicacy. He has an ambitious soul who would ask more; he has a hopeful spirit who should look in such an enterprise to be successful.
