Malcolm Gladwell — famous for <The Tipping Point> and <Outliers> — gave a TED talk
on variety of choice and happiness.
According to Gladwell,
it isn't about chasing a single best option —
offering the chance to choose through horizontal variety
is what actually makes people more satisfied.
So how do you actually build a service or product
that makes people happy?
