Did you learn some wisdom from your grandparents by example, like patience, strength, unselfishness, value of knowledge, love, action over words?
Journal how they taught you this. While I am typing this, one thing comes to mind for me. My grandpa told me that the most valuable thing he had to leave me was his good name, and my Father has told me the same thing many times. It is one thing that is hard for someone else to take from you. You can destroy it yourself.
