As parents settle into the new school year — a time for new schedules, new activities and new demands — the pressure to balance life and work is ever present. But to suggest there is some way to find a perfect ‘balance’ (i.e., to focus equal time and attention on work and home) is impossible in my mind. Or to put it more bluntly – the whole concept of work-life balance is bull.

I’m still a parent when I walk into work, and I still lead a company when I come home. So if my daughters’ school calls with a question in the middle of a meeting, I’m going to take the call. And if a viral petition breaks out in the middle of dinner, I’ll probably take that call, too.

And that’s okay — at least for me and my family. I have accepted that work and life are layers on top of each other, with rotating levels of emphasis, and I have benefited from celebrating that overlap rather than to try to force it apart.

I refer to this as the “Work/Life Mashup.” In tech-speak, a “mashup” is a webpage or app that is created by combining data and/or functionality from multiple sources. The term became popular in the early days of “Web 2.0,” when API’s (application programming interfaces) started allowing people to easily layer services on top of each other – like photographs of apartment rental listings on top of Google maps. There is a similar concept in music, where a mashup is a piece of music that combines two or more tracks into one.

One of the key concepts of a mashup is that the resulting product provides value in a way that neither originally did on its own; each layer adds value to the other.

Now, I’m not suggesting this is a guilt-free approach to life. People – and especially women – who try to do a lot often feel like they do none of it well, and I certainly suffer from that myself. But I have learned over time that how I feel about this is up to me. How much or how little guilt I experience at work or at home is in my control.

I also realize that the concept of a mashup is a lot easier (and perhaps only possible) for people with jobs where creating flexibility is possible. With these caveats in mind, here are some things to think about to create a work/life mashup early in your career: add value and don’t ask permission.

Everything is easier when you start by being great at your job. If colleagues and managers know they can trust you to deliver high-quality results – beyond what was asked for you – in the right company they’ll be less concerned with when and where you get that work done.

Then, when you need to leave work to do something for your personal/family life, even during work hours (like seeing a child’s class play, taking an elderly parent to the doctor, etc.) – just do it. Let your manager know what you are doing and why, and make sure you deliver results above their expectations. That will set the right precedent to give you the flexibility you need. Once you’re in a leadership position, it’s important to recognize your responsibility to give your teams the opportunity to thrive in a mashup world.

It’s essential for leaders to outline clear expectations & objectives, reward results and model the mashup. By outlining an inspiring vision and setting clear objectives for their teams, leaders can make it clear how individual work is connected to larger goals, and how to measure success in helping achieve those goals. Beyond that, as leaders we need to encourage our teams to stand up for what they need for their own mashed-up lives – and create environments where that is welcomed.

Leaders can effectively model the mashup for their teams. When I was a marketing exec at Yahoo YHOO , my manager, who was then chief marketing officer, left work at 5:30 every day so she could get home in time for dinner with her family. Not only was she consistent about leaving at that time, but she also made it visible to the full team that she was doing it, thereby effectively giving permission to others on the team to do the same. By modeling that something other than an “always on” work schedule was acceptable, my manager showed her team that she understood and valued the importance of both work and life outside of work.

The times when the mashup has worked best for me are when I find ways to creatively blend work and family together. This is what I like to call the “extreme mashup.” As it turns out, my family and my colleagues each have something to gain from the other.

When I was leading The Dealmap team, we stayed late every Wednesday for a few months working toward a big launch. Since I couldn’t get home to see my family on those nights, my husband (who also worked full-time, but not startup hours) would bring my daughters to the office after dinner with cookies for everyone in the office. Those days became known as “Workalicious Wednesdays.” My daughters were able to get a sense of what the startup environment was like from those visits, and the team looked forward to the weekly cookie drop-off.

This set-up also helped me show the team that a family-friendly work environment was encouraged, and for the next few years, various members of the staff would periodically invite members of their family to stop by the office.

More recently at, I was able to combine a work trip with a family vacation while the kids were on break from school. We took a week of vacation and then I brought the family along while I worked at two of our international offices. It was a great chance for my children to learn about the world, and for my staff (both women and men) to see that we are building the kind of company that encourages people to love their work and their families.

In fact, men are increasingly looking for ways to “balance” work and family, as evidenced by the actions of Max Schireson, former CEO of MongoDB, and it’s important that leaders embrace the fact that this is not simply a women’s issue.

Above all, I try to remember that life is about meaning – the meaning that comes from authentic relationships with those we love, and from worthwhile work that we believe in. People rarely lie on their deathbeds thinking, ‘I wish I had a nicer car,’ or ‘I wish I joined one more board….’ They think about the time they spent with the people that matter to them, and the legacy they left in the world.

It’s time to stop worrying about the perfect balance, and instead focus on being with people we love, and doing work that matters. Since there will never be enough time, a mashup might just be the solution, and leaders in every company have the power to make it a reality.
