This is an interesting trick, and seemingly contradictory to common sense. If you ask someone to do something for you, they are more likely to think a bit more highly of you. So if you find yourself with a client who is a bit hesitant to seal the deal or someone in the industry who you just can’t seem to get to like you, try asking them for a little favor. In order to carry out your request, they have to, somewhere in their mind, think that you deserve it. And once they acknowledge that you deserve their time, they will tend to like you just a little bit more.
