Michael Bungay Stanier, author of "Do More Great Work: Stop the Busywork. Start the Work That Matters," says people need to learn to say no and be willing to make mistakes. "One of the ways you become a successful entrepreneur is you build up scar tissue," Stanier said. "I have stumbled and fallen. I've failed to get along with bosses. I've been fired." Stanier offers suggestions for those eager to stop doing bureaucratic, time-wasting work and move forward with more meaningful projects.
