Do your best in whatever state that you find yourself in. The process is most important. The outcome is irrelevant but what matters is that you did not give up! You did not quit! You did not fall short of meeting your obligation. In whatever situation that you encounter do your utmost best.
If I am diagnosed with an incurable disease I "gambaru" with this challange. A single mother of 4 who can't pay the bill I "gambaru" until days get better. I loss a limb in a car accident I "gambaru" under the adversity.
