We hold ourselves back in ways both big and small, by lacking self-confidence, by not raising our hands, and by pulling back when we should be leaning in. We internalize the negative messages we get throughout our lives — the messages that say it’s wrong to be outspoken, aggressive, more powerful than men.

It’s not only working parents who are looking for more hours in the day; people without children are also overworked, maybe to an even greater extent. When I was in business school, I attended a Women in Consulting panel with three speakers: two married women with children and one single woman without children. After the married women spoke about how hard it was to balance their lives, the single woman interjected that she was tired of people not taking her need to have a life seriously. She felt that her colleagues were always rushing off to be with their families, leaving her to pick up the slack. She argued, “My coworkers should understand that I need to go to a party tonight — and this is just as legitimate as their kids’ soccer game — because going to a party is the only way I might actually meet someone and start a family so I can have a soccer game to go to one day!” I often quote this story to make sure single employees know that they, too, have every right to a full life.

At the same time, the world still isn’t very welcoming or respectful toward full-time at-home dads.
