Setting boundaries is one of the most important things you can do for yourself, both professionally and personally. Yet so many of us struggle to do it effectively. Why is that? Part of it has to do with the fact that we live in a culture that doesn't really encourage boundary-setting. We're supposed to be nice and accommodating, and that can come at the expense of our own needs and wants. But here's the thing: you can't be your best self if you're not taking care of yourself first. And that's why setting boundaries is so important.
