Think of yourself as dead, you have lived your life. Now take what’s left and live it properly. - Marcus Aurelius

Every soul, the philosopher says, is involuntarily deprived of truth; consequently in the same way it is deprived of justice and temperance and benevolence and everything of the kind. It is most necessary to keep this in mind, for thus thou wilt be more gentle towards all.

You want praise from people who kick themselves every fifteen minutes, the approval of people who despise themselves. (Is it a sign of self-respect to regret nearly everything you do?) (Hays translation)

Go straight to the seat of intelligence.
