Leonard Bernstein said this quote

To achieve great things, two things are needed: a plan and not quite enough time.

~ Leonard Bernstein

The point is, art never stopped a war and never got anybody a job. That was never its function. Art cannot change events. But it can change people. It can affect people so that they are changed... because people are changed by art – enriched, ennobled, encouraged – they then act in a way that may affect the course of events... by the way they vote, they behave, the way they think.

~ Leonard Bernstein

Any great art work … revives and readapts time and space, and the measure of its success is the extent to which it makes you an inhabitant of that world - the extent to which it invites you in and lets you breathe its strange, special air.

~ Leonard Bernstein

Music, of all the arts, stands in a special region, unlit by any star but its own, and utterly without meaning ... except its own.

~ Leonard Bernstein
