First, read the English article below.

People often want to be witty because they think they aren’t good conversationalists. But insecurity is the enemy of wit.  Good delivery often is the difference between a comment eliciting a laugh and falling flat. If you seem nervous or timid, your witty comment will not come across as well.  It’s important to remember that your perception of yourself is often inaccurate. You’re probably not as awkward as you imagine, and by letting yourself feel insecure, you’re actually hampering your ability to be witty. Paradoxically, the only way to overcome insecurity in conversation is to have more conversations! The key is engaging in low-stakes interactions (banter with a barista while you're waiting for your latte) as often as possible so that in high-stakes conversations (talking with the coworker you'd like to ask out) you're able to be witty. If face-to-face interactions make you nervous, try practicing your stories, puns, and other newly developed wit skills on social networking websites. Giving yourself a chance to work on your wit when you have more time to think might help you build your confidence so that you can be more relaxed during in-person interactions. As you become more confident, you’ll not only be able to move on when an attempt at wit falls flat, you’ll also know when to stop trying to be witty.  Shakespeare said “Brevity is the soul of wit.” Once you believe you’re witty, you won’t feel the need to try to make every comment witty — an effort that is bound to annoy or bore your conversation partner. Likewise, as you gain more confidence in your wit, you’ll learn when to quit. It’s always best to end a conversation on a high note.
