Mary Barra, chairman and CEO of General Motors, reveals that in order to keep a healthy work-life balance, you need to stick to your daily agenda. She asserts that if you’re in a meeting that’s overrunning and you have another engagement elsewhere, you have every right to get up and leave that meeting. Barra claims that women should never feel guilty for not sticking around later at work than intended in order to see to a personal commitment, especially if those personal commitments involve their children.
