Examine 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" and determine which of these emotions are present: anger, anticipation, disgust, fear, joy, love, optimism, pessimism, sadness, surprise, trust. If there are no identifiable emotions, reply with "neutral or no emotion".
