If your energy level is too low, you may not be able to do some of the things that are savers.

One person’s battery savers might be:

Walking
Reading
Painting
Gaming
Solitude
Wearing noise cancelling headphones
Running
Listening to music
Time with a special interest
Accomplishing a small task

Cancelling plans, prioritising yourself and only doing what is achievable
