I like to design by omitting, by gradually subtracting each element and weighing its loss. Try to leave out that essential gradient, alluring drop-shadow, distracting emphasis and superfluous, leading adjective.
Form follows fashion when it should follow function, but fashion consists of trends. Trends in form are transient, but functional design never goes out of fashion.
Subtract until only useful affordances remain.
This is the path to functional minimalism.
