The price you pay for your addiction to praise will be an extreme vulnerability to the opinions of others. Like any addict, you will find you must continue to feed your habit with approval in order to avoid withdrawal pangs. The moment someone who is important to you expresses disapproval, you will crash painfully, just like the junkie who can no longer get his “stuff.”
Others will be able to use this vulnerability to manipulate you. You will have to give in to their demands more often than you want to because you fear they might reject or look down on you. You set yourself up for emotional blackmail.
