If you have a question, someone else likely does as well.
Asking involves risk. Maybe someone will think you’re not smart enough to get it the first time, maybe someone will think you underprepared for the situation.
What others think has such an impact on each of us that we can become paralyzed with inaction. When was the last time another’s opinion alone made you better, or worse?
Get the information you need, and know that on a team, almost always you will not be alone in wondering about that question. By asking you make everyone better.
