In his 30s, Joe Moglia gave up on his dream to coach college football. In his 60s, he went back to get the job.
In those intervening years, he rose to the top of the financial field, eventually ascending to become TD Ameritrade's CEO.
Moglia successfully guided the discount brokerage through the "Armegeddon" of the financial crisis. But in 2008, after seven years as CEO, he stepped down and considered going after that dream job he left behind.
"Before I decided I wanted to go back to football, I really spent a lot of time soul-searching," Moglia told CNBC's "On The Money" in an interview.
As "part of the process," Moglia worked as a volunteer, unpaid coach at the University of Nebraska. "After a half season, I knew it was what I wanted to do, and I truly believe I had the skill sets."
