Well, what could I say! It’s stressful to be struggled, temporarily unable to solve a problem. But for me it is a good thing. Why is it a good thing?
Of course, it is a sign showing that there are rooms for improvement and that you are growing! Your life would be boring if there are no problems for you to solve. You are dying day by day if there is nothing more for you to learn, which means you are only to get worse as your age is pushing toward human limit.
Albert Einstein once stated that:
Once you stop learning, you start dying.
So ask yourself this question: “Are you getting any better than yesterday yet?” If not. Anything, just anything, get to learn at least a thing so that you are still living.
