Tim Tebow Talks Hosting 'Million Dollar Mile' and His Greatest Joy in Life

Tim Tebow has it all -- pro baseball career, 2 TV gigs AND an upcoming marriage -- but tells us what fulfills him the most has nothing to do with sports or being in front of a camera.

We had Tim on Friday's "TMZ Live" to talk about "Million Dollar Mile" ... his new competition show on CBS. He was just walking off the field from a spring training game with his NY Mets squad -- which got us wondering about which of his many, many jobs he finds more satisfying.

His answer was pure Tebow. You gotta see what he said about his Foundation and the work he's doing to change lives. Even if you weren't a fan from his NFL and U. of Florida days -- ya gotta admire him when ya see this.

Don't get it twisted, though, Tim's ALL IN for "Million Dollar Mile" too. The show, which premieres next week, is executive produced by none other than LeBron James -- and Tebow's not only the host ... sounds like he's head cheerleader. He explained why he needed some extra care during taping.

Gotta hand it to the guy -- he's juggling a lot professionally, and don't forget ... he also has to find time to plan a wedding with fiancée Demi-Leigh Nel-Peters.
