If you get chance watch this talk by Rory Sutherland (Ad man) about changing peoples perceptions and reality. Really clever and funny. There's loads of other talks as well so have a browse.

He's done another one about how the 'small stuff' is overlooked yet it's really these things that, in general, can have the greatest effect.
