很多解决方案，只想一步，不考虑后果。理想的方案，应该能用较低的成本，比如预期的 20%，解决掉 80% 的问题，且问题不会春风吹又生。

Use the test of time. Test whether you’re addressing the root cause of a problem, rather than merely treating a symptom, by asking yourself whether it will stand the test of time. Will this solution fix the problem permanently, or will the problem return in the future? If it seems like the latter, then chances are you’re only treating a symptom.
