Do you ask enough questions or do you settle for what you know?

I don't think that I ask enough questions.
There are so many things that I would like to understand and know more about, and while I do think about these things and even the questions I would ask, many times I just find it difficult to ask because I can't always put the question into words, I don't always know how to ask the question, or, I don't always find the time to invest in asking the question and learning the answer.
Sometimes also, depending on what is at question, I may be too intimidated to ask it.

But overall I almost always have more to ask, I just don't always actually do it.
So I do not ask enough questions, but I also do not settle for what I know, because I will continue to think about these things after, and maybe at some point in the future I will ask the questions I did not ask in the past.
