Emma Watson has learned to "quality control" people around her.

The Harry Potter actress - who is currently dating student Will Adamowicz - approaches her relationships differently as she grows older, and wishes she had done the same in her formative years.

"I wish someone had told me at 15, 'You accept the love that you think you deserve.' I would have approached my relationships completely differently if they had. I like this idea of quality control - that we don't have to accept just anyone into our lives. People talk about love as though it just happens to you - as though you're a victim in it all, when actually you can make good choices and bad. But women have a natural tendency to want to nurture and take care of men. I tend to date people who are quite introspective. I like deep thinkers."

Emma has had trouble with friends in recent years, struggling to find a sold group when she first went to the US to study at Brown University in 2009:

"My first two years at Brown weren't easy, not because I was bullied or because anyone gave me a particularly hard time, but just because, you know, without the collegiate system... and at Brown everyone does completely different things and very much chooses their own path, which is great, but it's also much more difficult, too. You're not with a group of people all the time at one time."
