The national Lean In Men's campaign focuses on how everyone benefits when men support women at home and at work. David Beckham, for example, has said about leaning in, "What matters is being a good father and a good husband - just being connected to family as much as possible. Being a dad is more important than football, more important than anything."
Matt Damon, a father of four girls, isn't afraid of leaning in - and rolling up his sleeves - either. "I probably worried more about changing diapers and bodily fluids and all that before I became a father," says Matt. "The reality is that once it's your kid, it's not a big deal at all." The campaign sums it up: Men leaning in for women and their families results in stronger marriages and healthier, happier, more successful kids.
