When repeatedly or overused in conversation or even in writing, words, phrases, and expressions fall in the lexical toolbox called cliché.
Overly heard or written, cliches make the words lose their impact, especially in an advisory or motivational manner, as we often encounter them on social media.
These two excessively used and famous sayings may get their classification as cliches:
“Be Positive”: Can or should we ignore some adverse facts facing us?
“Forget the past, worry not about the future, live in the present”: How can one forget the past? Only with past experiences and future dreams, living in the present makes better sense.
