G Gaynor McTigue, in his book says:

"Don't be the martyr.

You may think there's something noble and courageous in working excessively, missing meals, losing sleep, failing to exercise, depriving yourself of leisure, and basically running yourself into the ground. In fact, some industries and organizations actually glamorize this sort of destructive work ethic.

Don't fall for it.

In an emergency situation, yes, extraordinary effort may
be briefly required. But every day?

You're not doing yourself or your family any good by trashing your health and mental well-being. Stop playing the embattled warrior chasing after shortsighted gratification. If you want to be a hero, stay fit, eat healthy, live sensibly…and be happily more successful over the long haul. Why make yourself crazy?"

He has precisely pointed out the reason why all doctors in India are becoming crazy. 

Medicines cure diseases, but only doctors can cure patients. - Karl Jung

But I would say:

Medicines cure diseases, but only HAPPY doctors can cure patients.

Share with your doctor friend if you agree.
