On a date, especially early in a relationship, it's important to not dominate the conversation. It'll show that you're confident enough to let things progress naturally, and reassure your companion that you don't need constant attention.
Also, if you listen, you'll have the opportunity to get to know your date better, which is the whole point, isn't it? But there are times when the conversation picks up pace and you can enjoy some interesting back-and-forth chatter. Here's how to make the most of it.
When you speak clearly, it'll make your whole date go more smoothly. Conversation will flow better, which will make your date feel like you're easy to talk to. If you have sloppy speech habits (like a lot of young men), it'll take some practice to develop better enunciation. It helps to force yourself to slow down -- rushing will make you hard to understand. This is a skill that takes time to develop, so practice speaking clearly whenever you can.
Remember what we said before about smiling? It also applies here. If you smile when you're talking, it helps your voice sound more confident and happy. (This is hard to get used to, and might be uncomfortable at first. Practice in front of a mirror at home.)
Also, sounding confident depends on what you actually say. Give yourself a bit of credit up front -- assume your date is enjoying herself (unless she does something to indicate otherwise). Don't ask multiple times if she's satisfied with the restaurant or activity you've planned, which can be annoying and insulting. Don't apologize for being nervous, because it just makes you look more nervous.
Learning to modulate your voice will take time, but it's worth the effort to become a suave conversationalist. Need a confidence boost with quicker results? Continue on to the next page.
