Any quick general advice about first dates when you're still in the beginning of all this

I'm going on a sorta date, with a lady. Doesn't matter though, what I'm looking for is general advice, thoughts, ideas, on what to focus on when you're new to all this, and you're doing better but theres still that lack of confidence. I've been crushing it, at a lot of things in life lately, weigh less than I have in years, even lift, do yoga once a day, read more, work harder, have a good job, got a new car. But the ladies, they terrify me.
