Your work environment can directly affect your motivation and creativity, so it's important for you and your partner to both maintain your own identities through your work spaces in your homes. So, agree to configure separate work areas to foster your own ideas in.
This can be as simple as agreeing someone works at a desk and someone works at the kitchen table, or even distinguishing your spaces with your favourite work essentials like your preferred lighting, the amount of surface space you need, or little things that bring your joy like plants or journals.
