Burnout isn't always huge and obvious.
In fact many of us may experience acute burnout more often than we realise. It's a huge symptom of our world today when there are so many demands on us, pressures to do more and more, and to push ourselves harder
We are living in a time of ultra connectedness where we cannot unplug for long without people asking questions.
It's no wonder that burnout is talked about a lot in reference to introversion and sensitivity. It often occurs as a result of time/life/self-management issues in the context of a world that demands an infinite supply of more.
