If you focus on what is right in front of you, following what is right and reasonable with care, steadiness, and gentleness — if you don't mix in other distractions but work only to keep your spirit clean and pure, and stick close to what is right without hoping for rewards or fearing consequences — if you content yourself with simple, honest truth in everything you do or say, then you will live happily. And no one can stop you from this.
If thou shalt intend that which is present, following the rule of right and reason carefully, solidly, meekly, and shalt not intermix any other businesses, but shall study this only to preserve thy spirit unpolluted, and pure, and shall cleave unto him without either hope or fear of anything, in all things that thou shalt either do or speak, contenting thyself with heroical truth, thou shalt live happily; and from this, there is no man that can hinder thee.
