...[I]ron discipline does not preclude but presupposes criticism and contest of opinion within the Party. Least of all does it mean that discipline must be 'blind'.

True freedom is impossible without a mind made free by discipline.
Freedom like charity, begins at home. No man is worthy to fight in the cause of freedom unless he has conquered his internal masters. He must learn control and discipline over the disastrous passions that would lead him to folly and ruin. He must conquer inordinate vanity and anger, self-deception, fear, and inhibition.
The daily mindfulness, consistency, and discipline is ultimately more important than the amount of time. In other words, it’s more about quality than quantity. If you use 15 minutes effectively, you’ll accomplish more than you would be able to with two hours of unfocused, random actions.
