“We only do well the things we like doing.”

Bon, ben, dans un cas comme ça, qu'est-ce qu'on fait? On se crache dans les mains et on recommence!
1995 referendum concession speech.

Variant translation: When all your judgements are based on your own wisdom, you tend towards selfishness and fail by straying from the right path. Your own judgements are narrow minded and have no persuasive power or growth for others. It is best to consult a wise man when a fit decision does not occur to you. A wise man is a fair judge from an objective point of view. He is passing judgement for the benefit of others, not for his own sake. A judgement passed using only one's own wisdom is just like thrusting a stick into the ground and expecting it to grow!
Hagakure (c. 1716)
Context: It is difficult for a fool's habits to change to selflessness.... Because we do most things relying only on our own sagacity we become self-interested, turn our backs on reason, and things do not turn out well. As seen by other people this is sordid, weak, narrow and inefficient. When one is not capable of true intelligence, it is good to consult with someone of good sense. An advisor will fulfill the Way when he makes a decision by selfless and frank intelligence because he is not personally involved. This way of doing things will certainly be seen by others as being strongly rooted. It is, for example, like a large tree with many roots. One man's intelligence is like a tree that has been simply stuck in the ground.
We learn about the sayings and deeds of the men of old in order to entrust ourselves to their wisdom and prevent selfishness. When we throw off our own bias, follow the sayings of the ancients, and confer with other people, matters should go well and without mishap.

The Einstein Intersection (1967)

Lies: And the Lying Liars Who Tell Them (2003)
Context: If you listen to a lot of conservatives, they'll tell you that the difference between them and us is that conservatives love America and liberals hate America.... They don't get it. We love America just as much as they do. But in a different way. You see, they love America like a 4-year-old loves his mommy. Liberals love America like grown-ups. To a 4-year-old, everything Mommy does is wonderful and anyone who criticizes Mommy is bad. Grown-up love means actually understanding what you love, taking the good with the bad and helping your loved one grow. Love takes attention and work and is the best thing in the world.
That's why we liberals want America to do the right thing. We know America is the hope of the world, and we love it and want it to do well.

Context: We can be absolutely certain only about things we do not understand. A doctrine that is understood is shorn of its strength.
