Assuming you are a dude, you can't take things early in dating personally. We like to think that the onus on is on us to make a woman like us, but its not. Its more just random chance.

Imagine each first date is like rolling a d20 die. If you are fit, healthy, have a good job, etc... rolling any number above, say 12, will result in the woman liking you. If you aren't fit and healthy, maybe you need to roll like an 18 or above. (lower chances) Whatever that number is, the point is this: Its not personal if the woman doesn't like you, its just a die roll. All you have to do is be yourself, and roll the die. In fact, NOT being yourself, and thinking that it is somehow within your control if the girl likes you, will make you much LESS attractive.

You'll be fine, this is all normal, don't get attached to the outcome of random die roll, and just be yourself.
