Justin Timberlake loves trying new things.

The 33-year-old singer and actor believes it is important to learn from everything he does, so knows if he starts to repeat himself, it's time to do something different.

Speaking on the new season of 'Oprah's Master Class', he said: ''If I'm not learning from something that I'm doing, then that means I've done it before. Do something different, even if it's within the same medium.

''To try new things, that makes more sense to me than making a career out of doing the exact same thing over and over and over and over again.''

And the 'Mirrors' hitmaker - who is married to Jessica Biel - feels particularly excited and inspired when he embarks on a new challenge that takes him out of his comfort zone.

He added: ''I like the moment where I can look at everyone and say, 'I have no idea how to do this. Let's figure it out.'

You do that with a stage performance as much as you do a character on film. That inspires me. That motivates me.''

Other stars who will appear on the new season of 'Oprah's Master Class' include singer Lionel Ritchie, actresses Whoopi Goldberg and Sharon Stone, and 'Fargo' star Billy Bob Thornton.
