I had a teacher who stressed for me the importance of diction in terms of... I want to be very careful about how I say this... in terms of supporting one's voice when one is singing. In other words, if you hold on to your words, your voice will pull through for you when you're singing. So be true to your vowels.
I love to prune my roses. That's the one thing I really feel I do pretty well. Other things I usually, because I travel so much, leave to my gardeners who know what I love. But I do love to prune them, because you forget everything else. It's like if you're a painter, you can forget everything else while you're doing it.
