In the scriptures it is written that all men are born with gifts -- some this and some that. If you try and make a living at something you're not suited for you will be miserable and do poorly. If you pick the wrong major in college same thing. Or force your children to study fields that are not suitable for them they will be miserable and do poorly as well.
It is written in the scriptures "you will be judged in place of your nativity." This means that certain parameters go into effect the minute the natal cord is cut. What are these parameters? That's what the Harmonic Life Astrological Report will tell you. Freewill is built into our existence but knowing what we're naturally gifted at makes life more of a swim with the current than against it.

Look at some famous people's charts to see how descriptive they are of their talents. This would've been known since birth. This information could then have been put to use in picking school majors, jobs, etc.
