Instead of predicting, or following, the next interior trend, why not become it. Take everything that is deeply personal - culture, background, philosophy, etc. - and seek inspiration there first.
Not until those depths have been completely exhausted, should one contemplate looking further afield. I, for one, find nothing more irritating than seeing some WASP twenty-something on the Buddha trail. Don't be the interior design equivalent. Please, I beg of you.
