That’s great you know they’re a charismatic that’ll give you a baseline of how they’ll react. Do you know which of the 18 seducible personalities they are? Apply that charismatic seducing qualities and plug and play it to whichever of the 18 types of people who can be seduced they are. People tend to fall into more than one category. Act accordingly, and fulfil whatever it is that 18 personalities needs knowing that they’ll act as a charismatic. Separate yourself from acting as you normally would, and make yourself fit this description within their presence, but be mindful that depending on the environment or social structure you’re in (such as a college campus, work place) word may get around. This isn’t a bad thing. That is if you use your environment to your advantage. If you’re playing the long game (if you’re not I suggest something like a pick up artist book) ensure you plan all the way to the end. Also, make sure they’re even open to being seduced. Chose the right target. Don’t waste your time if it’s not going anywhere. You’ll know, by how they’re reacting if it’s working. Be brutally honest with yourself. If it is fantastic. If not cut your loses. Enjoy the experience and happy seducing! I hope this helps.
