Given the rapid pace of change in our culture, your capacity to generate questions, to select more valuable ones and pursue them, and to bring others into this process will have have far higher value in the twenty-first century than facts which have decaying half lives.

Good answers are still valuable.
If you have come to learn, you are. You may find the answer to your question or given your ability to act as ambassador to your own questions, others may take an interest in your work and may bring you an answer. There is no guarantee that the world will find you an answer, but once you have clearly articulated the question, you will know the good answer when you see it. Further, that answer will have a place and context in which to link and to remain in long term memory. Take the questions and keywords that emerge from your reflectivenss and use those words to hunt in the world's information systems for people and works that are relevant to your questions.
