Since I've made a mistake just now, i feel a little bit sad...:( After turning it over in my mind for the whole afternoon, it is still a failure...
The first attempt may fail, but we don't care about that, because we still have many chances to try it again.
We must find the reason that results in this consequence and keep it in mind...
Only in this way can we not make the same mistake!!!
I will keep fighting and make myself stronger and stronger...i believe i can make it!!!
