Live the example every day. Words are helpful, but actions are everything. Children are extremely perceptive, adults are transparent. "Do as I do".
If you are lucky, your words will come out of your children's mouths to their children someday and then you will live forever.
Be sure you are remembered for the right things. Love, Kindness, joy, forgiving, justice, honesty, giving, fidelity, laughter and love again (needs to be said twice). That is your legacy.
