So sad Today, I should have earned more but I forget an unsure rule maybe that is my desire more so do that. Then I missed great chance though I earned more what I expect but still sad. Because I have a goal. But the event pass by It is useless to think about Only adjust my mood. We should know how to put down it so be happy. I know it is human shortcoming but It is also a lesson to overcome. Dont let it influence my mood.
