Stop trying to impress.
You are there to show them what kind of person you are, not to show them the kind of person they’re looking for.
This starts with having the right mindset about yourself. If you’re rushing through your date, checking off everything you think they want to see/know about you, constantly thinking about what they’re thinking about you, you’re bound to fail.
Concentrate on yourself first to show off your inner confidence and contentment within yourself. Once you’ve achieved this, it won’t feel like such hard work!
