My advice is to get to know yourself in and out Childish Gambino is able to tap into his creative side because has gotten to know his self and know what he likes and what he doesn't like. He is able to completely be himself no matter where he is or who he is around. Like when he got the award and shouted out the group Migos he didn't care who was around. He was being completely his self. It will take time and experience but once you start with that step the sky is the limited.
