Your greatest assets

As a person or as a business, what are your greatest assets?
Take a moment if you will. Think about your answer.
Did your answers include money in the bank, a great product, a house, a car, impressive sales?
Do you feel compelled to protect and develop these assets?
Another question: what could you lose that would shake you to your foundations? What, if taken away, could bring you to your knees?
Your family, health, values, team?

My final question: if the two lists are different, how much time and energy do you currently invest in the former vs the latter?
