On this week's show we heard from Eduardo Verastegui, the lead actor and producer behind the touching film Bella. He mentioned how, as a rediscovery of his faith, he refuses to act in films that offend “his faith, his family or his Latino culture.” That decision meant he went without acting work for four years. But now Bella has been born.

What are the non negotiables that you’ve decided on? What 'lines in the sand' have you drawn in your own life? Like Eduardo, have you ever put a stop to something that was going on in your life, out of principle?

• Maybe like Eduardo it’s to do with refusing certain roles in the entertainment industry
• Maybe it’s to do with maintaining relationships – turning your back on a busy lifestyle and taking one full day off each week to spend with family or friends
• Maybe, like Eric Liddell, you’ve drawn a line in the sand about working on Sundays
• Maybe you refuse to conduct business in a certain way, selling a product etc
• Maybe it’s to do with sexual boundaries.

When have you taken a stand about something…and how did it work out for you?

On another angle - when have you regretted not drawing a line in the sand?
