If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

"To travel is to discover that everyone is wrong about other countries."

解释：向外物游览就要要求外物的完备，向自己内心求取，则能充实完善自身。
