Confident because of our caution
No man is disturbed by things, but by his opinion about things.
No man is free who is not master of himself.
Be free from grief not through insensibility like the irrational animals, nor through want of thought like the foolish, but like a man of virtue by having reason as the consolation of grief.
Books are the training weights of the mind.
Things themselves don't hurt or hinder us. Things simply are what they are. How we view these things is another matter.People think what they will think; it is of no concern to us.
