In modeling, there are ways you can iterate towards the right solution.
关于建模，以下方法能让你一直朝着正确的解决方法前进。

Firstly, never add methods that might be useful in the future. Be minimalist, get away with as little as possible.
首先，严禁增加将来可能有用途的方法。确定系统的最小化，尽可能地小。
Secondly, don't be afraid to recognize today that what you did yesterday wasn't right. Be willing to change things.

其次，不要惧怕挑出你昨天的错误。积极地改变。

Thirdly, be patient and enjoy the process.
第三，要耐心，同时享受其过程。

Ultimately you will arrive at a system that feels right. Until then, keep iterating and don't settle.
基本上，你的系统会很不错。 接着，一直这样，直到彻底解决。
