General principal of growth: Growth must mean that we are alive.
How incredibly, ineffably wonderful that is! We all grow at a pace that is perfect for us. Anything that is force fed or artificially hastened will incorporate weaknesses. So let us accept our natural rhythm, and the beautiful design of our unique biological equipment, namely our shoulders, arms, wrists and fingers. Size and strength are rarely an impediment to our joyful growth.
With correct awareness there are always alternatives to any situation.
Please don't be tempted into trying anything like the young Robert Schumann, who devised some mechanism to "strengthen" his fingers, and ended up breaking one or two!
Heaven forbid that you suffer such a tragedy as Paul Wittgenstein, for whom Ravel composed his awesome Left Hand Piano Concerto.
However, accidents do happen.
I have had three separate "Practice Stopping" injuries to my hands over the years.
Fortunately, only one hand at a time, and all fully recoverable.
Please look after your precious body.
Growth in the study process seems to follow a pattern of peaks and plateaus. The study of the new followed by a period of assimilation. Quite often it might be felt necessary to have a complete break. Go ahead, be positive about it if you feel it. You can rest assured that you will return to practising with freshness and renewed vigour.
The Way is still there.
It is critical for your growth that you supply the right nutrients. A varied diet of pieces of the correct degree of challenge that suit your taste and regular study to help your technique grow. To this end, I would recommend a series of Musical studies, not the dry "Technique in Isolation Ward" type that leave the musical soul parched.
After all, what use is technique if it is not contextualised?
Karl Czerny comes high on my list, he had a wonderful understanding of "relaxed hand fingering", which the studies mysteriously impart to whoever takes the trouble to learn them. I will supply in a separate section some dry isolated technique exercises for you.
