The essence and beauty of life is when you are able to procreate and pass on life to others who, in turn, do same, too.
Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.
Genesis 2:24.
As you aged, other things you cannot do, like your aspirations, plans, projects, and your legacy, pass it on to your offspring who will live your dream come through.
Do not struggle to achieve all in your old age.
For what you had before I came was little, and it has increased to a great amount; the Lord has blessed you since my coming. And now, when shall I also provide for my own house?”
Genesis 30:30 NKJV
Allow your children to live their own dream. Give them the space and time.
When they are successful, you will be delightful. And you will live your old age with a feeling of fulfillment.
Part of living the best of life is seeing others live the best of their lives, especially your own heritage.
