people can remain irrational longer than you can remain sane

John Maynard Keynes famously observed that markets can stay irrational for longer than you can stay solvent. Building on that idea, people can remain irrational longer than you can remain sane, or people can stay irrational longer than you can stay sane. That's why it's important to have people to rely on to help you stay steadfast in your convictions. When it seems the world has gone mad, it is your tribe, your community, your network, your family that helps you as you express your fear and anxiety and stress, even as you go out into a world that seems hostile to you and what you believe.
