Respect the opinion of others. It is based on knowledge that you may not have.
“Everybody is ignorant, only on different subjects.”
– Will Rogers
We keep learning new things, even if we don’t think we are.
“Real knowledge is to know the extent of one’s ignorance.”
Prepare your mind to receive the new knowledge that is coming in. Be open and respectful.
Even if you think the new knowledge is wrong, take the time to understand it and verify it before you reject it.
In the end, you always pick what you want.
Else then a religious book, do you read a book more then once?
