It’s a trite saying that “the only thing constant is change”. Apparently written by the Greek philosopher Heraclitus, the book that contained this phrase was lost to history and exists only in fragments.
And each day brings us a reminder that, no matter how much stays similar, things are changing. The times, Dylan sang, they are a-changin’. And it’s something that each of us should learn to cope with.
It does us little good to cling hopelessly to how things were. The best course is forward, and we all have to figure it out along the way.
