2. More of certain types of learning can take place when one tries not to teach.
3. Some things are learn-able, but not teachable.

5. What is true for children is probably true for adults too.
6. We think we learn from our failures and other peoples successes, but it is the other way around.
7. We grow from calamities, not from virtues.

9. Students can learn more from each other than from the teacher.
10. We learn to ski in the summer and swim in the winter.
