The 18th would add down to a "9".

The type of numerology that I am studying is called Chaldean numerology.  It has alot of focus on Karma which is determined by the date of birthday as the primary number.  To get the number for your personal characteristics, you add the two numbers together to get a single number.  You were born on the 8th, you would not have a compound number.  This is supposed to mean you have no Karma and are completing your re-incarnations on this Earth, provided you do not create any new karma in this lifetime.  

Your name also has a number based on the Chaldean method.  You probably would have a compound number between your first and last name.  There are other methods of numerology that uses a different key and would produce a different number.  My advice is to do a Google search for the different methods and see which one rings true for you. you can learn alot on-line free of charge.

the number 8   turned sideways is the sign of infinity  ,the balancing between haven and hell two  spheres one on top of the other ,the 8 can also mean maintaining control over the physical material world.power admin/leadership and greed .

number 8 is not evil as many wrongly believe it to be.... it is in my opinion only inauspicious if it comes in conjuction with number 4 ......4 and 8 should not occur together and that is considered to be a sign of fate dealing with a human being who hasnt done much wrong,..

i gratefully accept my power
and use it for the good of the whole.

i discriminate among options and choose
what is most constructive for myself and others

i respect the energy i find in others and direct it
wisely and justly when given the opportunity

i have the self confidence to make important decisions.
