You can always tell the difference between someone whose knowledge comes from having done things compared to someone who has only learned about them from reading or hearing others talking about having done them.
What they teach has a certain power and value whereas what the other teaches is stale and lifeless.
Once upon a time, we respected someone who had a lifetime of doing and then retired to spend their time teaching what they had learned. Not just in education, but in all areas of life.
Now we have teachers who learned from other teachers who learned from other teachers. We are surrounded by the stale and hold it up in admiration.
WTF are you talking about? I don’t follow at all, but I think you’re making the mistake of thinking you know what a 100 thousand word book is about based on 400-500 words..........CONTEXT!!!!!
