Dr. Dai: The length of life is given by heaven, and the width is created by ourselves.

We cannot change the length of life, but we can change the width of life;

We can't change the weather, but we can control our mood;

We can't change our looks, but we can show our smiles.

We can't change our height, but we can control our weight;

We may not be beautiful, but we must live beautifully!
