This is the arc of life, with a peak somewhere in there, but for the most part, we miss it.
When you look in the mirror today, you might say to yourself, ‘Gawd, you are looking beautiful today.’ You might as well admire this presentation because next week you will look slightly altered. As I did yesterday when I noticed my hair had ‘suddenly’ become much greyer than I remembered. If you can, avoid the expression ‘for my age’. That negates the little bit of self-love you created upon complimenting yourself.
