Brent Gleeson was unhappy working in finance, so he quit his job to join the Navy.
But that wouldn't be the only time he would make a significant life change in pursuit of happiness. Upon returning home from combat, Gleeson and his wife decided to end their marriage, leaving him as a single father.
"That created a lot of turmoil in my life," he told HuffPost Live's Caroline Modarressy-Tehrani, referring to his divorce. "So focusing on my own personal happiness took a far, far backseat to things like raising my son."
It was the skills he learned in the armed forces, he explained, that helped him find a sense of balance in this trying time.
"[Being a Navy Seal] gives you the ability to manage stress and anxiety better," he explained. "It helps you really put things into perspective, and focus on the things in life that really matter."
