To begin, put yourself in the places where creativity is already happening. Show up and be seen. Go to a coffee shop or a conference or maybe make the move to a new city altogether. Join the scene, and find that group of people you need to succeed. Just as Hemingway sought out key influencers in Paris, you can seek the influencers and gatekeepers in your own industry. Impress them, become their apprentices, and let them teach you. Win them over, and these people will welcome you into the scene.
