Nature has given to each conscious being every power she possesses, and one of these abilities is this: just as Nature converts and alters every obstacle and opposition, and fits them into their predestined place, making them a part of herself, so too the rational person is able to finesse every obstacle into an opportunity, and to use it for whatever purpose it may suit.
Marcus AureliusPast and future have no power over you. Just the present - and even that can be minimized.
Marcus AureliusIt is not the actions of others which trouble us (for those actions are controlled by their governing part), but rather it is our own judgments. Therefore remove those judgments and resolve to let go of your anger, and it will already be gone. How do you let go? By realizing that such actions are not shameful to you.
Marcus Aurelius
