Even if you are not a believer, there is great pragmatic behavioral stuff in Torah. A reminder in this article from The Jerusalem Post.
'Hey, what are you doing with that tuna-and-pickle sandwich?" asked a puzzled Gerald Schwartz of the Arab prisoner. "I'm surprised you aren't keeping Ramadan," continued Schwartz, a bearded Orthodox social worker, referring to the the Muslim month of introspection and daytime daily fasting.
"I'm a secular Muslim," said Mahmoud, who was incarcerated for a misdemeanor unrelated to any political activity. "And also I am not capable of the daytime fast."
"You can't, or you think you can't?" challenged Schwartz and urged Mahmoud to try for one day.
Schwartz later recalled: "Mahmoud fasted one day, and went on to keep the entire month of daytime fasts. He was a nice guy. He found his own strength, began to believe in his ability to change, cleaned up his act, and never returned after being released. This principal applies to all."
