Hi Starchini - I have made a study of numerology over the years and while I am just an amateur I share your fascination with number patterns.
This is a nice birthpath you have there but you are forgetting one important thing - your year of birth is really 1981. That is 1 + 9 + 8 + 1 = 19 (1 + 9) = 1
So now you take your full year of birth, 9 + 9 + (1 + 9 + 8 + 1) = 9 + 9 + 1 = 19 = 1. Your birthpath is 1, a life mission of leadership and initiative. Even if you try to avoid leadership it will seek you ought. You have the life energy to start projects and trends and affect others by doing so.
When you are doing further research on your birthdate - or any date - keep in mind the full four digits of the year. Here's another example: your personal year is found by adding your month and day of birth to the current year.
9 + 9 + (2+0+1+2 = ) 5 = 5 personal year. This is a year in which changes that you feel you need to make will be supported by the universe - in fact there may be many more changes than you are comfortable with, or the rate of change may seem very fast and drastic. Have faith that this is all for a purpose, some things have to be moved out of the way to make way for growth and new developments in your life.
This year could involve extensive travel and/or a geographic change for you. These influences of 5 are likely already evident but will intensify as you get to your birthday in September when the vibration comes into full play. "Go with the flow" is the motto for 2012 into 2013 for you. Enjoy the journey!
