One of my great aunts made it to 102. She pulled DH and I aside one day and told us that she and her DH had been great dreamers. They had scrimped and saved and not enjoyed themselves and had said they would take trips and do things as soon as he retired.
Well, less than a year after her DH retired, he died. He never got to do any of the things they had dreamed about doing together.
She told us to have fun and enjoy our time together and not treat it as endless; anything could happen to either one of us at any time. Save our money, yes, get ready for retirement and be well-prepared for bad times and rainy days.
But don't forget that we are only promised now and that we need to live and love each other and enjoy our lives together.
It was, I think, the wisest advice anyone ever gave DH and me. We have lived our life together by those words.
