My life hack is to appreciate the positive and disregard the negative. And that also translates well to dating and meeting women. Focus on their good. Never be gratuitous, it MUST come from the heart. But the easiest way to charm a girl of any age is to recognize her good points. Besides, it shows you pay attention. And that you care. Most women appreciate this. It obviously doesn't guarantee a thing, but when you represent yourself as a caring and observant person, it represents you well. At the least.
