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.
To follow, without halt, one aim: that's the secret of success.
Success depends in a very large measure upon individual initiative and exertion, and cannot be achieved except by a dint of hard work.
Although one may fail to find happiness in theatrical life, one never wishes to give it up after having once tasted its fruits.
