They waste their time & energy crying, complaining, getting angry & upset, instead of trying to understand & look for solutions
"It is in the midst of difficulties that man develops his intelligence because, in order to overcome them, he must observe, think and become clear-sighted. Nature has put difficulties here and there in life to develop her children's intelligence, but the children do not develop: they waste their time and energy crying, complaining, getting angry and upset, instead of trying to understand and look for solutions. Obviously when they are exhausted, they calm down, but the difficulties are still there; their energies are gone but their problems remain. What a weird method!
I ask someone, 'How long did you cry? - Three hours. - Did you solve the problem? - No. - Well, next time, cry just ten minutes. As you would miss not crying, do it, but no more than ten minutes; and once the ten minutes is over, start thinking!'"
