(According to Mr. Larry King who has been in his profession for 50 years in the very competitive society of America, to be a welcomed guest or an interviewee [at least in his show] you need humor and a chip on the shoulder [among other things].
If you make a joke but lack a genuine sense of humor, you cannot heal others.
If you have complaints like most of workers, taxpayers, consumers, and voters, but you know there are unhappier or more helpless people in the world, your experience may make you a healer in future.
Jesus Christ made people think about what He said or did, so that people would come to change their views on life and the world, and thus come to find a reasonable way out of suffering.
If you find one day suddenly that you have been loved by someone you have never realized, mostly your mind is healed.
The issue is that you should not be that someone in opposite meaning or with adverse affect. You do not have to be a healer, but you should not be a factor of someone else's suffering.
One in 100,000 people, there must be someone who loves you or needs you, in a sense fatally.
It will not take 50 years to meet such one, if you go out with faith without sitting around and just waiting for a nice guest; you cannot be a king or a queen in America so easily.)
"AND THE GOD OF LOVE AND PEACE WILL BE WITH YOU"
