Game design requires knowing what to keep and what to discard; not all good ideas fit together.
The most important thing is to be able to think, to be able to see, to be able to judge what you see.
做好事如同背负重物而登山,志向虽已确立,但总是担心力不从心;干坏事如同骑马下山,虽然未加鞭,但却欲驻足而难以自禁。
The best way to be happy is to follow your heart.
