Robert Cialdini explains reciprocity: when you give something meaningful, surprisingly good, and tailored to someone's needs, they feel obligated to return the favor. Even small gifts work if they hit those three marks.
If you invite me to a party, I should invite you to one of mine. If you remember my birthday with a gift, I should remember yours with a gift. In the context of obligation, people say yes to those they owe. Your first strategy is to act by giving to people in an unselfish way. If what you give is meaningful, if what you give occurs at unexpected levels of quality or speed, and if what you give is personalized for their particular challenges, for their particular situation, their particular needs, the return on investment will be maximal. Even small things that you provide first, provided that they have these three characteristics, will produce the same yearning desire on those who receive it. To want to give back to you. To want to give back to you. And Eina hosted. Now you can't. Alamal.
