Learning through suffering

"In the same way, it is often through suffering that we learn. But it is far better if we can learn without suffering, or learn from the suffering of others (without making others suffer, of course). However, some people take the fact that suffering is often the route to learning to mean that suffering is somehow essential to all learning, or that the person who learns by suffering has necessarily learned more than the person who has learned without suffering. While in general this may be true, it is by no means always true. Many people suffer and never learn. Others learn quickly and avoid the need to suffer altogether."
