As Chrizzle says, do be yourself. I think that's really important. Perhaps aspects of yourself you can enhance and emphasise for the cameras - but that should be the full extent of it, despite the fact that BB is more and more profoundly becoming a platform for aspiring celebs rather than people there purely for the experience.

If you're not yourself, and your true personality comes out as the weeks go on (which it most probably will do), you'll prove yourself to be inconsistent, as well as quite fake.
