To follow, without halt, one aim: There's the secret of success.
When a small child, I thought that success spelled happiness. I was wrong, happiness is like a butterfly which appears and delights us for one brief moment, but soon flits away.
Play the last measure very softly.
Where there is no heart there is no art.
To strive tirelessly and at all times to reach one's goal - therein lies the secret of success.
The right to happiness is fundamental.
