It surely does.The sweetnes of a sweet can only be realized after U have one in your mouth.An egg may contain all the nutrients that U need for ur health but so long it is not boiled or fried U might not enjoy having it.Words no doubt contain all the ingredients,it might inspire one to a great extent but when a person shows them in its action it better shows all.A coach can teach all the techniqes but one untrained player if perform better in the field is certainly a better example to all.

actions speak louder because it usually can't be lie, words are more like to be lie, so people believe the action more than word. Lying by action is more difficult than words. As a matter of fact, it is not that hard to follow the apothegm, when you are going to tell lies, shut your mouth up and wait until you feel the lie is worthy.

It's just reality..
