Persistence.
In Jerusalem , a female CNN journalist heard about a very old Jewish man who had been going to the Wailing Wall to pray, twice a day, every day, for a long, long time.
So she went to the Wailing Wall to check it out, and there he was.
She watched him pray and after about 45 minutes, when he turned to leave, she approached him for an interview.
"I'm Rebecca Smith from CNN. Sir, how long have you been coming to the Wall and praying?"
"For about 60 years".
"Sixty years! That's amazing! What do you pray for?"
"I pray for peace between the Christians, Jews and the Muslims. I pray for all the hatred to stop and I pray for all our children to grow up in safety and friendship."
"Sir, how do you feel after doing this for 60 years?"
"Like I'm talking to a fuckin' wall."
