Your article has a more pragmatic view to work life balanced than the ones discussed in other articles I read so far.
Like yourself, I also merge work and life in an integrated way. They are inseparable.
Quoting an insightful remark that I fully agree in your article:
I remind myself that the lows are necessary to make room for the highs.
What I also like is the concept of excitement in joy form. As you wisely point out, life must excite. Joy is a natural state.
