We sometimes say we need a change,
As a change is good as a rest
But often fail to ponder
If change is for the best.
And if we change too many things
In way, or shape, or form
Then constant need to change occurs
And change becomes the norm.
And change becomes our mentor
As change succeeds each change
And every changeless constant
That stays unchanged seems strange.
