Laughing at our mistakes can lengthen our own life.
Laughing at someone else's can shorten it.
- Cullen Hightower
If you put it in study:
Laughing at our errors and mistakes can lengthen the benefit of failure experience in our study life.
Laughing at someone else's can shorten it!
Hence, to laugh more at your own mistakes and learn from it....
Rather than laughing at someone else's and do nothing about it!
