Guy Kawasaki, in his book called “Enchantment“, presents how to become likeable towards others. Below, you can find a “one page” summary of the book but I do invite you to read the book and enjoy the details / stories / experiences that lead to his conclusions.
If you don’t plan to read the book but you have 1 hour to watch the presentation of the book, check this funny and engaging video:
