Also a lot of people dont seem to know how to complement someone. Complements are good, but only if you do them right. They are best done small, and casual at first. "Did you get a haircut? I like it." "That (Article of clothing) looks great on you." "You're always so stylish." Once youve got a few dates under your belt and the mutual interest is clear you can move on to things that are a bit more intimate. "Your eyes are beautiful." "I love hearing you laugh." "I always look forward to spending time with you."

Notice nowhere in there did i put "Wow your so hot." or anything like that. Thats boring. Meaningless. Stuff like that is fine if your having sex, and want something to say in the heat of the moment, but if you are trying to win someone over emotionally be more interesting. Just the simple fact you are interested in them makes it obvious you think they are physically attractive. You don't need to hammer that point home over, and over again. Its fine to complement appearance, but have an angle. Actually notice things about the person.

Everything is situational. Complements especially, and they have multiple purposes. First of course is to express interest, and to make that person feel good about themselves. Most people understand that. But 2nd is to make it clear you are paying attention. Notice changes. Notice what doesnt change. If you like someone it shouldn't be hard to do. Do they look a bit tired today? Sure would be nice if you'd been paying attention, and knew what type of coffee they like so you can buy it for them. Its not a hard thing to ask in casual conversation. "I prefer peppermint tea personally, what about you?" Then remember their answer. Then when you know what they like buy it, give it to them, and say "I was getting myself a drink, and figured I'd pick one up for you too."
