Hmm, it seems like you've been losing sleep over this beautiful girl you met. Now you want to impress her before anyone else does right? Well, my friend i can only give you a few tips that are being practised by people all around the world, but don't expect too much from me because not even Lord Almight himself can tell you the exact trick. So with no much further time wasting lyrics, i present to the the trick of the trade!
1) Maintian hygiene. No matter which company's clothes you wear, no matter how cheap/expensive they are, just maintain hygiene at all times. Women are too concerned about their men not being clean. They find it repulsive when you don't bathe on a regular basis or have huge finger nails that are filled with dirt. So put cleanliness to practise
2) Show confidence. You'll hear a lot of blogs talking about confidence, but you'll see very less people actually putting it into practise. For most times, you might believe that you are confident but it'll only take a handful of unfortunate situations to bust your bubble. Being confident at one time is one thing and being confident at all times is another. So go read some confident boosting material online and start putting it into practise.
3) Be flirty and romantic. Dating is all about having fun and if you aren't having fun then you aren't the person whom she wants to date. She'll just find somebody else. So be as playful, flirty and romantic as you possibly can and you'll go head over heals for you
4) Develop a sense of humor. Just like us men, even women love to laugh( because they are also human, remember!) so develop a good sense of humor. If you aren't really humorous, try to do some homework and while you are taking to this girl, just divert your conversation to the point where you can crack your joke.
Hope this helps you impress the girl you have in mind!!! All the best
