I didn't feel any sadness around me. It reminds me to step by step rather than to imagine to have a good result.

It also helps me to realize don't expect too much before you pay more attention on it and take action to do a thing. I gradually learn to comfort myself it doesn't matter I can continue to study and treat it seriously rather than to be full of tricks.

I always think I can do it while I didn't  having made sufficient efforts to do a thing.

I won't blame myself just got an experience form this thing. Never feel you will have a good result and without any actions.
