For the tweet "#lesson from @KevinHart4real #book I'll apply:  In #life U always have a choice.  Kev had grimey things happen &amp; he #chose #optimism", classify the emotional tone using the following list: anger, anticipation, disgust, fear, joy, love, optimism, pessimism, sadness, surprise, trust. If no emotion is discernible, state "neutral or no emotion".
