Black or White
You should know and remember that nothing is hardly ever black or white. Sometimes the explanation or demo will be based on a choice for something and the reason for that might not be explained, but this does not mean that there is only one way of doing a certain thing, or that other explanations are wrong. You should keep an open mind and learn how to analyze whether something is safe and meets a certain goal. If the answer is yes then it’s a correct way of doing something.
