In business, as in life, there are times where things really do need to be complicated. however, so often they are complicated for the wrong reasons. Unless something needs to be complicated, try as hard as you can to simplify it. Simple and elegant explanations are difficult to create (and that's why people don't bother creating them!), but they are much more effective than legalese and trickery.
