Some are driven to follow in their parents' footsteps, while others loathe the very concept. For Theron Shan, it's a moot point. In keeping with Jedi strictures against attachment, Theron's mother, Grand Master Satele Shan, sent her infant son to be raised by the Jedi who trained her, Master Ngani Zho.
Over time, as it became evident that Theron was not Force sensitive like his mother, he abandoned any notion of becoming a Jedi. Eventually, he joined the Strategic Information Service, using his adventurous nature and unique skillset to become a trusted field agent for the Republic.
