Could it be that it’s not actually imposter syndrome, but rather the world we live in and culture we work in that makes women feel like we do?
The only people who get upset when you set boundaries are the ones who benefitted from you not having them.
Boundaries are important in every facet of life and they are especially important in business. While saying yes (or, not saying no) to an unaligned request might not hurt your business, in the long run, always saying yes--whether coming from a feeling of lack or fear of being disliked--runs a large chance of negatively impacting the health of your business in the long run. When you are running a business you are responsible for what gets done and what doesn’t. That includes what you say “yes” to and what you say “no” to. What you do always comes at the expense of something else.
Setting boundaries is not an option, it’s critical to running a successful business. It’s important to determine what’s most important, set boundaries accordingly and take the necessary actions to enforce those boundaries. Doing so sets up your business for success.
