Maybe the idea of being a rockstar or being the one who's recording or playing, sort of doesn't really matter as much anymore, when you're surrounded by great musicians who bring their spirit, their own talent.

There's never a better way of living than just improving our quality of life.

I'm a self-taught musician, so I never really had the restrictions of any one instrument. I would always just sort of pick up instruments and make noise with 'em.

That's what we do on 'Entourage.' We embed ourselves in legitimate authentic moments so wherever the action is happening, we're taking pieces from that red carpet.

I'm a filmmaker, I'm a storyteller, an entertainer, if you will, so what can I do to participate? Well, I'm not a scientist; I'm not an expert on environmental law; I'm a guy that can tell stories. So I always look for a way to communicate ideas and help to spread excitement for change.

I want to show people that environmentalism can be fun!

We can't be naive and think we can go it alone; we must humble ourselves and commit to routine and collective actions. This is just one reason why I am thrilled to be working with the UN Environment as its Goodwill Ambassador.
