Educate yourself but try not to play the “Mr. Know It All” game in a meeting with a manager or a team meeting. It could get messy. Most people are very insecure especially ignorant managers.
Read and get smart about who you are dealing with and play one down most of the time even if you are asked for advice. Let them say what they want and always mirror/validate, label and ask a question.
You read too much!
Hmm , too much? How so? and let them talk.
