Matt Barnes: My Message to 17-Year-Old Self ...

Kobe Bryant's letter to his 17-year-old self was all about advising him how to handle his money -- warning him how massive wealth can screw up relationships.

We asked him outside Penthouse nightclub in L.A. Wednesday night -- and his answer was interesting considering the situations he's been involved in over the past year.
