Often Misattributed

These circulate widely under the same name, but don’t hold up:

• “You have power over your mind — not outside events. Realize this, and you will find strength.” A modern paraphrase. The idea is thoroughly Stoic (see 8.47 above), but the sentence itself does not appear in the Meditations.
• “When you arise in the morning, think of what a precious privilege it is to be alive — to breathe, to think, to enjoy, to love.” Widely shared, but not in the Meditations. The genuine morning passage (2.1, above) is far less sunny.
• “The happiness of your life depends upon the quality of your thoughts.” A loose modern rewording of 5.16 (“the soul becomes dyed with the colour of its thoughts”).
