Thoughts on ch7 "lighten up"

In chapter7, "lighten up!", the importance of finding something to celebrate and to laugh at was mentioned. Before reading this chapter, I thought laughing in a hard situation is not only difficult but also inappropriate because then others might think you are not taking that situation seriously.

However, the chapter gave me some good reasons to have happy celebration in tough situation and that is...
It can break the spiral of depression and stimulate creativity.
It can give people the chance to step back and look at the issue with wider perspectives.
It can reduce such emotion as fear and tention.
It can reorganize the team.

These great effect of celebration could be seen from the many company that was used as examples in the chaper and also from the story of Endurance which successed in doing "celebration" in tough situation and overcoming that hardship. It seems "celebration" really works but I still think it is definetely not an easy thing to do especially in an tough situation.
