Astrid already had her calculation written down in front of her. She used her wand to copy what she had written in the air just as the professor had showed them. She wrote:

7/25/2054
7 - 25/7
7 - 7 = 0
First Challenge = 0

First Challenge Age = 36 – 7 (Life Path Number)
First Challenge Age = 29
Age Range = 0-29 yrs

My first Challenge number was zero and took place between my birth and 29 years of age. The textbook says the following for the 0 Challenge:

ZERO (0): Also called the Cipher Challenge, it stands for all or nothing. The symbol of the circle, it can be full and empty at the same time. You have full free will to and choice to form your own world as one filled with love, compassion, integrity, vision, and to do great works. When governed by the 0 Challenge, do not take this time lightly. Nurture your desire to make the world a better place in consideration of your Destiny Number and the higher laws of universal order. The person with a 0 Challenge is said to have an 'old soul,' especially if you carry a master number as his or her Soul Number. You are expected to make choices that honor a higher awareness and foster spiritual growth on the material plane.

"I'm not sure just exactly what that means for me." she said "I need to think about it some more but I think that it means that I can make my world just what I want it to be as long as I keep the greater good in mind.."
