If this is for a resume or LinkedIn, frame the time off as a choice made to pursue specialized training or to return with "renewed energy and a deeper understanding" of your field.
Use high-quality photos of nature or stillness (like parks or quiet solo walks) to reinforce the theme of "unplugging".
Real rest is not just "not working"—it's an intentional interruption that allows your brain to connect dots you didn't even know existed.
