This is a Latin phrase from the book "Strength of Will" by E. Boyd Barrett. He is talking about a young Jesuit, John Berchmans, and saying he was very dedicated towards any goal he set himself. "In him the maxim was verified to the fullest: 'Suae quisque vitae pictor est; artifex hujus operis est voluntas.'"
