You asked something nobody has before, because you covered thousands of questions with only just one. Thus, to answer your question, one must do a deep research. Your question trembles the hearts of teachers, because it reminds them of the beginning of their journey when they spent time reading hundreds of articles. Can you feel it? The spirits of the dead pioneers are not happy, because they see that you also have the spirit of a pioneer. You prove it with your ultimate question. Now, you must take the journey into the unknown and find the answer yourself! Maybe this is the link that will help you start, but be warned! The path is blurry! You must pay attention to all the clues. Those may lead you to other questions, but try not to forget the first one! Who knows when the answer to it will be revealed?
