I don't believe in regrets. Everything happens for a reason.

"The past is never dead. It's not even past."

Wrong life cannot be lived rightly.

事情过后议论别人，身在局外议论局内人，是做学问的人最容易犯的毛病。在事后议论别人，往往将聪明人说得极其愚笨；身在局外议论局内的人，往往将困难的事情说得极其容易，这两种毛病都是由待人不忠诚、不宽容而引起的。

"The past is a foreign country; they do things differently there."
