That old saying your parents told you when they were too tired to explain anymore. Sort of sticks with you.
Did you know that curiosity doesn't kill you at all? (by the way, what does kill you is listening to bad or false advice and information) It is the impetus for future learning. Perhaps you recall seeing a toddler, learning, and always asking "why?" The reasons that adults tire to answer this question is that there is a limit to the answers that can be given where agenda's are at stake, esp if they are not your own. That is where the answer "Because I said so" originally comes from. When education lacks, authority will usually answer a persons curiosity, with the aim of squelching it.
It was questioning boundaries in the first place that got the industrial age started, and the information age we now live in that replaced it. It was questioning all that was accepted that caused us to harvest the power of electricity and other elements.
A distinct lack of curiosity is causing many problems with the western world at the moment. Now,it seems, we have questioned enough. That is why the two political parties insult the intelligence of all their constituents with simple platitudes, hoping that you won't be curious enough to question it.
It has long been the plan to convince you and I that asking why, being curious, will only make you....... miserable? Less happy?
JW's and the Governing Body know this all too well. The plan was/is to keep you thinking that their answer = your happiness. When it is in fact, your questions that = your happiness.
In thinking about the meaning of life, a quest that usually tries to honor "answers", such a quest, such a path, is actually lined and marked by the smaller questions within ourselves along the way.
It seems to me upon reflection that sometimes, we are so busy looking for answers, we forget the subtle questions attached? Instead of asking "Why am I here?" why not ask, "What do I look to read? To do?" There is a mile marker pointing you in the right direction.
What are you curious about? There is the meaning of your life. Yeah, it will require some fleshing out, but the smaller questions are usually more important then that big old "Why am I here" thing. And at the end of those "one step at a time" questions, is your destiny.
