Don't judge each day by harvest you reap but by the seeds you plant

Don't judge each day by harvest you reap but by the seeds you plant.

- Robert Louis Stevenson

When something happy happens or I get a reward, I feel it is a good day.
On the other hand, when something unhappy happens or I lose, I feel it is a bad day.

Although I think that it might be true in the short-term, it is a big misunderstanding in the long-term.
Because whether I get a reward or not is the result of the accumulation of what I have done.
It is not the result of the day.

So what I do today is the most important of all.
I may feel it is a bad day if I had a bad result even though I studied hard.
But I shouldn't give up, because it is not a real result. It is only a process.

Keep trying hard whatever happens today!
