Great design solves problems, not just looks good.

Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.

最终，我们记住的不是敌人的话语，而是朋友的沉默。

书是一个永远不会让你失望的朋友。
