I've personally seen the Servants By Design product change the lives of people through the power of understanding. Knowledge of one's design leads to a desire to understand others and that is the catalyst for both compassion and love.
If you want to improve your relationships and communicate more effectively, you've come to the right place. All it takes is about an hour of your time and a few dollars - investments well worth it.
TIP: It's quite common to dismiss the validity of the results because of personal bias. Look it over and then hand it to a close friend or spouse and ask them to let you know how accurate they think it is. You will probably be surprised by their analysis.
You will not be sorry, but if you are - I'll make sure you get your money back.
