Question:
Most of you by this time in your lives believe you have lived long enough to have a fairly wide knowledge of the world and how to live life. By what you have read, what are the dangers of believing this? How does one get past being stubborn and opinionated about something they believe, even if proof to the contrary is provided? Also, how do preconceived notions work against one being able to develop a fully-formed standpoint?
