No enterprise can exist for itself alone. It ministers to some great need, it performs some great service, not for itself, but for others; or failing therein, it ceases to be profitable and ceases to exist.
Calvin Coolidge
We cannot do everything at once, but we can do something at once. Calvin Coolidge
