Always follow these two rules: first, act only on what your reasoning mind proposes for the good of humanity, and second, change your opinion if someone shows you it's wrong. This change of mind must proceed only from the conviction that it's both correct and for the common good, but not because it will give you pleasure and make you popular.
Marcus AureliusThink of yourself as dead. You have lived your life. Now, take what's left and live it properly. What doesn't transmit light creates its own darkness.
Marcus AureliusAt day's first light have in readiness, against disinclination to leave your bed, the thought that "I am rising for the work of man."
Marcus AureliusIt is not the weight of the future or the past that is pressing upon you, but ever that of the present alone. Even this burden, too, can be lessened if you confine it strictly to its own limits.
