At 90, Tony Bennett feels like he's "just starting out" — but the music legend still has plenty of wisdom to share, with nine decades of life under his belt.

In an interview with TODAY, Bennett revealed the best advice he's gotten.

"Always be honest with the audience. Never fake it. Give 'em everything you got," he said.

He added, "Stay happy, have a great life, enjoy the fact that you're alive, and enjoy every moment."

Bennett also shared his greatest accomplishment (his hit "I Left My Heart in San Francisco") and his dream collaborator (Beyonce) in the video.
