Curiosity may have killed the cat, but also got man to the moon, helped build devices to look back in time to the beginning of the universe and caused me to ask my wife on our first date. Curiosity has an element of risk and with it the related exhilaration. It does not always bring us what we expect, but if it did the dedicated would never be elevated above the normal.
Curiosity is a question. How far can I go? How high can I climb? What will happen? Who is the best? What is the cure? Is there other life out there? What is the meaning of life? These are the kind of questions that drive us as individuals, groups and nations to explore the edges of the known and into the realm of possibilities and to test the concept of the impossible. You will never know unless you try.
What are the questions that drive you forward? If you do not know the question, the curiosity, you will never know when you have found the answer. The question takes us from what we do know to what we will know and hopefully to the next question.
If we were not curious we would never explore. My encouragement to you is to be an explorer. Find the edges of your ability and see what is past them. Look for new areas of knowledge to expand your mind. You will also never know how strong you are physically or emotionally until you test the boundaries. They both need to be exercised to improve and you need to realize the improvement to push you to the next level.
Finally, the only way to love and be loved is to take the risk of giving the best of yourself. Yes, curiosity and commitment help develop the best relationships of your life. Love is a continual exploration of your own depth and hopefully the most fulfilling journey you ever take.
