The Cambridge dictionary describes this quote as:
“A change of work or occupation can be as restorative or refreshing as a period of relaxation”.
Very true though.
This often used quote is bandied around on any number of occasions to explain actions which may appear quite extreme in regards to a simpler solution.
If you find that something isn’t working for you whether it be a job, a relationship or a simple thing like a health and fitness regime, sometimes a complete change is as good as the rest you might have if taking a break from whatever it is that seems to be getting you down or wearing you out.
