Careers are a jungle gym, not a ladder.

I am saying that I was able to mold those hours around the needs of my family, and that matters. And I really encourage other people at Facebook to mold hours around themselves.

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.

The more women help one another, the more we help ourselves. Acting like a coalition truly does produce results. Any coalition of support must also include men, many of whom care about gender inequality as much as women do.

We need to talk more openly about mentorships and sponsorships. Women don't get the mentoring, and particularly the sponsors, they need to succeed as much as men.

You know, there has never been a 24-hour period in five years when I have not responded to e-mail at Facebook. I am not saying it's easy. I work long hours.

Being confident and believing in your own self-worth is necessary to achieving your potential.
