For me living in awe is living in your Sweet Spot - where your passion meets your purpose.
What is the difference between living in your Sweet Spot and living in the zone of "Scraping By Just Fine Ma'am"? In your Sweet Spot you feel a sense of awe and mystery. You feel like you can never get enough, never know enough because it is not something to get on top of, its something that takes you somewhere that you trust because you feel so alive in your Sweet Spot. If you feel like you can never get enough of something, you know there is nothing else out there for you to do.
I remember when a friend of mine was getting married and someone compared her marriage to shopping for earrings and asked "I understand that you might find a pair of earrings you really like but aren't you scared that down the line you'll find another pair of earrings you like better?"
The bride-to-be told our friend that if she spent her whole life with her husband it would still feel like it could never be enough time with him. She felt like she just couldn't get enough of him. So she would not be looking for anything else.
I guess one way to know you are NOT in your Sweet Spot is by noticing that you are constantly looking for something else. If you need to be a Know-It-All you may be driven by a need to be superior to others. Living a life with the purpose of outsmarting others is not really that smart. You are selling yourself short if you believe that your purpose is only to be better than others.
