It is relevant to me to ask questions, and to make those questions relevant to the answer I am expecting. Asking the wrong question will usually cause me to receive answers which are irrelevant to what I was needing to know.
For example, the question “What is love?” is not going to get you the answers you need. This is because if love was clearly defined, then no one would need to ask the question. If there are many definitions given by a dictionary or the culture you live it, then you are unlikely to get the answer you need.
I am at a loss when it comes to understanding some words. What I have found most effective is to listen or read what other people are saying. Then I can ask a question specifically about something they said. If they ask a question, I can ask them questions about more specifically what they meant.
No one should ever be afraid of asking honest questions. To do so is to turn off your brain. No one can function at all without thinking a little bit. We do this for basic things like reading, writing, shopping, or even watching a movie.
Without questions, there is no understanding. Without understanding, there is no relevance. There are no stupid questions, just stupid people who tell others not to ask questions.
