What Helps to Weather YOU and What Buckles YOU?

In my book “Just a Common Lady,” I talk about how a motherless female child made her way through life by tenacity and trying to adjust to the expectations of others.  The child had one upheaval after another and managed to take life’s bumps into a reasonably adjusted childhood.  In another of my books entitled “AS I AM,” a male child handles a catastrophic accident and basically becomes about as helpless physically as a human being can be.  And yet, in both cases, the children grow to be happy and productive adults.

Just how much is too much for a child?  Does it depend upon the age of the child or the support system available or the professional assistance the family can afford?  Why do some children buckle in times of stress and others seem to weather the storm and come out winners?  Do you think it’s genetic, environmental, chance?
