Just watching David DeAngelo's Advanced Dating Techniques program, I really like his distinction between Seduction and Attraction:
“Seduction implies tricking, being dishonest, and hiding your motives. Seduction also implies a scarcity mentality. It implies you lack the confidence that women will be attracted to you, and therefore you must resort to covert manoeuvres.
Attraction on the other hand is working on yourself, improving yourself to the point where women are magnetically attracted to you. That attraction mechanism gets pushed inside [the man] very quickly.”
It's important to understand how seduction works and when it's appropriate and inappropriate. But when a man invests significant energy into his own personal growth, he becomes a man who attracts women naturally. This is more authentic, has a more powerful impact on his whole life, and a more positive influence on the lives of those around him, than simply learning a bunch of eduction techniques ever will.
