Opening yourself up to receive. Receive compliments. Do not brush them off as a pleasantry. Let a compliment sink in and feel the gratitude.
Open up to receive a gift. Understand what that person went through to get that for you. The work they do to make they money to pay for the gift. The time they took to go through the store or search online. The skill to wrap it and write your name on it.
Know you are worthy of everything that is coming your way and accept the gift that life has to offer.
