Words are not enough, you need actions to prove them.
Just saying is not enough, you need to keep your promises.
Tell others is not enough, you need to live it when no one is looking.
Actions speak louder than words after all.
If you do not live by what you say, by what you believe, or maybe even by what you think you believe, words will be just a collection of letters strung together uttered in recognizable sounds, most importantly, hollow. Hollow as a log, as vacant as a void.
