Since my retirement(退休) from teaching music in 2001, I have spent a good deal of time painting as an artist. I actually began drawing again in the summer of 1995 when my father died, so perhaps I was trying to recover from the loss of my father, or maybe it was just that it brought back memories of him. In any case, I drew pen and ink animals and landscapes(风景画) much influenced(影响) by Krenkel and St. John for five years.

For some strange reason, I had been waiting until my retirement to start doing watercolors again, but as soon as I walked out of the school door for the last time I picked up my brushes and rediscovered Andrew Wyeth, who quickly became my favorite artist. I had looked through all the art books I had on my shelves and found his watercolors to be the closest to how I thought good watercolors should look. So I painted landscapes around Minnesota for three years and tried out many other types of painting. However, watercolors remained my first choice, and I think I did my best work there, showing my paintings at a number of art exhibitions.

Art is now together with my piano playing and reading. There is a time for everything in my world, and it is wonderful to have some time doing what I want to do. As Confucious once said, “At seventy I can follow my heart’s desire.”
