Many sports coaches, business leaders and even parents give motivational pep talks in an effort to strike an emotional chord within the listener that compels them to act in a certain, desired way. The speaker wants his words to resonate within a listener, like a tuning fork vibration that penetrates your soul.
Resonate is a verb which means “to evoke or reinforce a sympathetic or simpatico feeling, emotion or thought.”
When words convey a message that correspond to and coalesce with what you already believe, they strengthen what you feel, what you think, and how you act. Words and ideas resonate within and amplify your power. Use resonance as a turbocharger toward greatness.
