This is a list of things I noticed from ways I improved my social/seduction skills:

1- Don't compliment the person, compliment what they have/do:

Don't say, "You are sweet" or "You look beautiful today", if a girl is dressed beautiful, tell them they dressed beautiful, in other words tell them what is sweet, not who is sweet.

2- Look excited about the way they look/act:

When you say "I like your shirt, it looks beautiful", don't say it like you are telling a fact but look a little excited, look bright and colorful like her shirt's brightness and color reflects from your face.

3- Always be honest, don't compliment someone just to compliment:

If someone is dressed nice, tell them, but don't tell them they are dressed nice just because. Don't be a liar to compliment.

Overall, be natural, confident and honest, you know, same things that apply to almost any dating advice.

But don't do it often, don't be "Mr. Compliment", be natural about it and only do it when the person looks accepting of a compliment because trust me, if rule 3 applies, if it is something to be complimented, they probably expect that compliment and will gladly accept.

Why compliment? It is a conversation starter in a nice way if you share a space with someone (like a classroom).

For example, I met my current date by complimenting a plain black shirt, but it looked really good on her and she looked confident with the way she dressed. You know how complimenting that ended? She complimented me back, told me I look colorful today, this way you can also know what she likes or finds nice.

I know it is a bland post, just wanted to share my experiences this last month in summer school. Just complimenting a plain black (but really fitting) shirt ended up with a date for me, so I wanted to help others my own way. Hope it helps!
