"Jack Dorsey, the cofounder of Twitter and founder of Square, has an interesting approach to his weekly routine. He has divided up his week into themes. Monday is for management meetings and "running the company" work. Tuesday is for product development. Wednesday is for marketing, communications, and growth. Thursday is for developers and partnerships. Friday is for the company and its culture.9 This routine helps to provide calmness amid the chaos of a high-growth start-up. It enables him to focus his energy on a single theme each day instead of feeling pulled into everything. He adheres to this routine each week, no exceptions, and over time people learn this about him and can organize meetings and requests around it. TACKLE"
