Work life balance isn’t just about time, is it?
If it is simply the nature of your work (long hours), or how it takes shape (the creative process/collaboration), or perhaps the nature of its delivery (craftsmanship), you might not always have control over your time.
I work with people in highly demanding professions who are always conscious that work will take up a disproportionate amount of their time.
For them, the answer is equally about managing their energy.
Which requires a very good sense of awareness.
The question is: are you aware of how you use your energy?
