Expert writing Tips
Best practice
When using "cannot be too", ensure the sentence clearly conveys the idea that exceeding a certain degree of the described quality or action is undesirable or unnecessary. This phrase works best when a limit exists beyond which the action or quality becomes counterproductive.
Common error
Avoid using "cannot be too" in situations where there is no practical upper limit to the quality being described. For instance, saying "One cannot be too kind" is generally less effective than "One should always strive to be kind", as kindness is rarely seen as having a detrimental excess.
