It can ruin your life only if it ruins your character. Otherwise it cannot harm you—inside or out.
To suffer change can be no hurt; as no benefit it is, by change to attain to being. The age and time of the world is as it were a flood and swift current, consisting of the things that are brought to pass in the world. For as soon as anything hath appeared, and is passed away, another succeeds, and that also will presently out of sight.
Consider the whole universe whereof thou art but a very little part, and the whole age of the world together, whereof but a short and very momentary portion is allotted unto thee, and all the fates and destinies together, of which how much is it that comes to thy part and share.
Wipe out the imagination. Stop the pulling of the strings. Confine thyself to the present. Understand well what happens either to thee or to another. Divide and distribute every object into the causal (formal) and the material. Think of thy last hour. Let the wrong which is done by a man stay there where the wrong was done.
