Glover Quin is a Pro Bowl safety with the Detroit Lions and he's saving 70 percent of his take-home each season to invest in well-known, publicly traded companies.

Quin and his family lived on the remaining 30 percent, approximately $6,000 per month and $72,000 per year over the first three seasons of his career.

Occasionally, Quin had a higher budget if he got what he called “unaccounted-for” money for doing an appearance that wasn’t planned. He and his wife would use that money on vacations and other potential luxuries they didn’t initially budget for. Other than that, it was always about the plan.

“I’ve always trusted in the plan and never really let other people sway me away from it,” said Quin, now a safety on the Detroit Lions. “I like to call it tunnel vision. It’s not good to have tunnel vision on the field, because you need to know what’s going on around you, but when you’re in life, especially in this field, you need to have tunnel vision, because you see so many guys around you buying cars, buying jewelry, doing this, spending money, talking about the money that they spend.

“And you’re sitting there like, ‘Man, I’m living off this much money every month, and this cat spending this much money every day.'"

When his contract expires after the 2017 season, Quin will have earned more than $21 million, before taxes, in his eight-year career. Quin estimates that his private portfolio could match the money he's made in the NFL.
