As "GAMBARU" is very common and usual concept in Japan, Japanese often make mistake when estimate the work/job which they must do.

As Japan won the war against Russia with the "GAMBARI(noun)", they thought they can also beat USA with more "GAMBARI(noun)" and had lost.

As I am rather older generation, I would say "I can do it" when I think "I can do it with "GAMBARI".". Most of the case, I could achieve the work and sometime I could not. This would be a good advice for the people who are going to work with Japanese.
