You need to feel that you're making a difference.

Endless data show that diverse teams make better decisions. We are building products that people with very diverse backgrounds use, and I think we all want our company makeup to reflect the makeup of the people who use our products. That's not true of any industry really, and we have a long way to go.

When you want to change things, you won't please everyone.

I was grateful that Facebook already had generous bereavement policies . Now Facebook employees receive 20 days paid leave to grieve the loss of an immediate family member and 10 days for an extended family member. I'm proud that we're able to do this and I hope more businesses do the same. Only 60 percent of private sector workers get paid time off after the death of a loved one, and then it's usually just a few days. Workers and families deserve better than that.

In those same 10 years, women are getting more and more of the graduate degrees, more and more of the undergraduate degrees, and it's translating into more women in entry-level jobs, even more women in lower-level management. But there's absolutely been no progress at the top. You can't explain away 10 years. Ten years of no progress is no progress.

Communication starts with the understanding that there is my point of view (my truth) and someone else's point of view (his truth). Rarely is there one absolute truth, so people who believe that they speak the truth are very silencing of others.

When people are really suffering, and we know they're suffering, that question can be a very difficult one. Inadvertently, I think without anyone meaning it, it communicates a lack of empathy.
