Fluent shapes. Designing type is like driving a car. If you drive a car, you always take the curve in a natural way. If you draw a curve (of a character) on paper, this is exactly the same. The curve starts smoothly, never out of a sudden. While driving a car, you don't start turning the wheel when you are already in the beginning of the curve. A while before you arrive in the curve you anticipate by leading your car gently in the right direction. Think about driving a car when you are sketching type on a paper. 

流线型。设计字体就象开车。你在开车的时候，总是会以自然的曲线过弯。当你在纸面上绘制一条曲线（或是字符）的时候，也是同样的道理。曲线平滑的开始，而不是陡然出现。开车时，你不会在已经到达了弯道口之后才开始打方向盘，而是在你预计即将进入弯道的时候，就开始慢慢的将你的车引入正确的方向。当你在纸上画草图的时候，多想想你是怎样开车的。
