Wondering about what does it take for someone to say "Yes". You have come to the right place. An exemplary book "Influence", contains six such principles of persuasion that are relevant till date. I have added a pinch of neuromarketing & cyberpsychology in it. As a bonus factor, There are marketing examples at every step. Enjoy with coffee and let me know how you feel about it ;) Link for the blog is https://medium.com/@tanishabatra19/she-said-yes-but-why-6eeb6e68981a
