I guess for me, balance isn't about treating your time like a pie chart and dividing it into equally sized slices for you, the kids, work, and so on. It's about the quality of how you spend your time, not the quantity--are you being present and focused on whatever you're doing while you're doing it? I truly believe that's how you can be the best version of yourself, whether you're in work mode, mom mode, or wife mode. When I know I'm giving my undivided attention in each of these areas, I don't feel so guilty about the time spent away from them.
