No one can predict the future.
We just spend our time on doing somthing as the routine. Perharps, something gonna happen in front of us. No one knows what and when we have to force that. But... if some incidents happen, there is only one thing we can do that is "DON'T BE PANIC AND SOLVE IT CONSCIOUSLY." Consiquently, we can pass it easily and successfully.
Don't let your thought and your panic dismay you effectively. - #iyoux_feels_depressed
