Brahms believed that there was no need to publish absolutely everything that Schubert ever wrote.

But, on the other hand, if Schubert were alive today, he would find even richer fields to plow.

Particularly at around the age of 70 you reach a stage where you have to be very careful. If, at that point, you abandon the work you have been doing, there is a good chance that you will just collapse and drift.

When you go out onto the stage, all the preparation has to be forced into your subconscious. For the moment of the performance, we all have to return to a new level of unconsciousness. All the reflection and all the doubts have to be laid aside before you start.

Unfortunately, it happens all too seldom that you really disappear behind a work, that you are no longer audible as an interpreter.

What concerns me, is the general social tendency to enforce a level, above which nothing rises and stands out.

One has to get through a big pile of mail every day. I don't pass my letters on to a secretary; rather, I try to take care of all of them myself.
