Prince William has said he wants to be out and about doing things when he helps out the charities he supports.
The prince said he realised being seen at events and shaking hands could be important, but added that he doesn't want to be a Royal "ornament".
In July, William climbed a mountain with a group of homeless people and said it was a challenge he enjoyed.
He said he finds projects like that are much better for him and for the people that he is working to help.
Prince William said: "Obviously you take a little bit of a gamble that sometimes it's not going to have the big effect you want but, even if it changes one person's view on something for the positive, then, as far as I'm concerned, it's a success."

The prince often represents the Royal Family at public events, also called engagements.
William said he was "inspired" by the work of his parents - Prince Charles and Diana, Princess of Wales who died in 1997 - and also the Queen.
He added: "You could just turn up and open things - and don't get me wrong, there's always a good reason to do that - but it's about bringing some other things into it as well."
