Imagine you were now dead, or had not lived before his moment. Now view the rest of your life as a bonus.
Nowhere can man find a quieter or more untroubled retreat than in his own soul.

Why should any of these things that happen externally distract thee? Give thyself leisure to learn some good thing: cease roving to and fro.
This is enough. Do not add, And why were such things made in the world?
