_Quit_, "to go away from" is not the same as _stop_.
_Quite_ means "entirely," "wholly," and should never be used in the modifying sense as if meaning _rather_ or _somewhat_. "Quite a few" is nonsense.

Such expressions as _right now_, _right off_, _right away_, _right here_ are not now in good use.
_Same_ should not be used as a p.r.o.noun. This is a common usage in business correspondence but it is not good English and can be easily avoided without sacrificing either brevity or sense. _Same as_ in the sense of _just as_, _in the same manner_ should be avoided.
_Score_ should not be used for _achieve_ or _accomplish_.
_Set_ should not be confused with _sit_. To set means "to cause to sit."

_Think_ should not have the word _for_ added, e. g., "It is more important than you _think for_."
