I realized that I am not a superhuman. I could not do everything just in a single time. I could not afford to make an output in one single moment. This teaches me to do things singly. To be productive from something before moving to another. A thought in my mind was built that no person could make a better result out of a thing without putting it into focus and giving it priority and concentration. We cannot serve two masters at a time. Better to do it one at a time.
