Stage fright is my worst problem. A voice is very intimate. It's something of your own. So there's always this fear, because you feel naked. There's a fear of not reaching up to expectations.
Listen to what others tell you about your voice. If you're only singing to please yourself, you might as well just sing under the shower. But if you're singing for others, you are reliant on them to ask you to sing.
I'm most impressed by the Russian writers, so I love reading the works of Tolstoy and Dostoyevsky. Another author who has informed the way I think is the French philosopher, Blaise Pascal.
Singing provides a true sense of lightheartedness. If I sing when I am alone, I feel wonderful. It's freedom.
