I don't know who wrote this but it is remarkably pertinent:-
We have two lives, and the second begins when you realise you only have one
Or when we realize we have gained the ability, strength and will power to start taking control over our lives. There is sometimes a transition point between how life is treating us -- and how we are treating life.
I have one life, but I made a "mid course correction" at age 51. I celebrate 2 birthdays - my physical birthday that was given to me - and my intentional birthday - which is the day I chose to start my life over my own way instead of what was dealt to me. I am so much happier in this 2nd half of my life. (Presuming I will live to be 102. )
Very apt. I would say the best one begins when you realize you have only one. There are no do-overs.
