I discovered several years ago that it is my choice to live happy or unhappy. And that my environment does not make me. So I changed my response to greetings;
You- ” How are you?”
Me – “Better than yesterday”
I decided that my today is always better than yesterday whatever happened yesterday.
My Lord and Savior, Jesus Christ, taught me not to worry about tomorrow because there is enough for today if I don’t waste it on yesterday and tomorrow (Matthew 6:25-34). So I do it that way.
We can live a worry-free productive life
