But when it comes to higher things, such as friendship, such as love, such as kindness, there you can never make enough sacrifice. He who had the ideal in his heart, for him always sacrifice is small. What sacrifice he does is always small. It is the one who has no ideal who will weigh and measure and see if it is even or uneven. "What I give is even with what I take, or there is no balance in it." There is his practicality; he calls it wisdom. It is not wisdom, it is cleverness. Wisdom stands higher, above it all. Wisdom does not come by practicality. When a person says, "I will guard my interest against every attempt made by others," he is a different person. That person is greater who trusts, who risks, and who can make sacrifices.
