According to Psychology Today, "Many argue that some of the most important time to develop creativity and help spark innovation does not occur at work. It occurs in the hours and days we are away from our jobs."
To fully take advantage of time away from work, some tips from author Brie Schmidt include to wake up early (ugh), avoid filling the time with chores (yay!), and plan your upcoming (or post-vacation) week in advance. (Laura Vanderkam recommends Fridays in general for this weekly planning. Here's why.)
Whether you're taking a weekend off or a longer break, I highly recommend leaving yourself good project notes. Then, when you return to your creative work with renewed energy, you can easily dive back in.
