痛苦+反省=进步

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.

在数学中，旅程与目的地同样重要。

译文：奢靡一发不可收拾，勤俭方能长久安乐。奢侈为凶，节俭为吉，这些征兆可以看得出来的。赏析：成由勤俭败由奢。家庭的成功离不开勤俭的好习惯，浪费铺张迟早会败掉万贯家财。勤俭持家会让家庭越来越兴旺发达，奢靡无度让家庭走向衰落，变得越来越凶险。
