The ThroughlinesLife Personality Test and website grew out of the book Throughlines—The Life of Your Personality:A Guide to Personal Awareness and Contentment by personal coach, author and philosopher Don Snedeker. Don spent thirty years working with families and individuals, and the book and test are the products of experience and deep reflection, having observed hundreds of children growing into adulthood and eventually having their own children, and seeing how their personalities did not change regardless of circumstance. Their parents’ personalities also remained the same, even when parenting and other challenges came their way. There is something in each of us that determines, influences and sometimes controls who we are, and when we know what that is, we will make better sense of life and why we each feel the way we do. We will know where to look for the problem areas as well as why we experience joy when and the ways in which you experience it.
