To regret the past, to hope in the future, and never to be satisfied with the present: that is what I spend my whole life doing

There is no doubt that even the greatest musical geniuses have sometimes worked without inspiration. This guest (inspiration) does not always respond to the first invitation. We must always work, and a self-respecting artist must not fold his hands on the pretext that he is not in the mood. If we wait for the mood, without endeavouring to meet it half-way, we easily become indolent and apathetic. We must be patient, and believe that inspiration will come to those who can master their disinclination.

It is already a great thing if the main ideas and general outline of a work come without any racking of brains, as the result of that supernatural and inexplicable force we call inspiration.

The muse doesn't come without being called.

Inspiration is a guest that does not willingly visit the lazy.

Sometimes I observe with curiosity that uninterrupted activity which, independent of the subject of any conversation I may be carrying on, continues its course in that department of my brain that is devoted to music.

Where the heart does not enter; there can be no music.
