How many times have you listened to someone speak and heard them use a word or an acronym that you weren’t familiar with yet you didn’t ask for an explanation?
Is admitting you don’t know something a sign of weakness or is this actually a sign of strength (the self confidence to not be afraid to admit you don’t know everything)?
You can continue to pretend you know everything and continue to stagnate or you can ask for clarifications and continue you to grow.
I would rather ask the question even if it meant something were to interpret the question as a sign of weakness than to keep quiet and continue to be weak.
Have a great day!
