I have a question that I have been meaning to ask.
What question are you curious about?
I have been asking myself the same question for a long time now.
If you feel unclear about something you should ask a question. It's better to be informed than to make a mistake out of ignorance.
What is the meaning of life?
It is good to ask questions, but some questions are only meant to be answered by yourself. Only you would know the answer to that because you have to find meaning in your own life.
