Very literally, my 5 children- Who now have spouses and children of their own. In my world, this is the purpose of humanity — that is the “piece of me” that now will continue throughout the future millennia as my posterity continues. It is who I am, a Mom.
But clearly, I think your question stirs something more than just DNA and our reproduction success ( or failure for some people — sarcasm intended).
When I hold the child's chair that my grandfather built in the 20’s for my Mom, I feel closer to someone I never knew. It is a part of him. His hands, his heart, his caring for a daughter he would leave less than a month later and never see again.
The painting my Dad created in the 60’s while taking “ I dare you to take this art class “ throw-down from my Mom because he was too busy for hobbies, shows a rarely shown artistic gift that hangs on my wall. I miss you Dad.
My husbands gold medals from his athletic youth tells his grand-kids — I wasn’t always fat and old, I was awesome.
So if you haven’t put anything out there by now… you better get busy. It’s your voice, your signature — what you see, how you feel about life and those you love.
