After working for over 3 decades for small, medium and large businesses, I can only completely agree with this statement. Although have I met compassionate people in the business world, the business world iself has never been about compassion. Business is very competitive. It's about striving and winning, or at the very least, simply striving.
There are places you can find compassion, but business is not one of those places. Consider a friend, a church or synagogue, a support group, even a pet . . . any or all of these are capable of providing emotional support. And when you are ready to compete again, get back into the "game" and try again and do it even better the next time.
