From my perspective, the primary task of a man is to stand on his own feet so that he will not brother others to support his life. Besides, learning to be prudent and careful when engaging in meaning work is an important lesson itself, whose effect can be manifested in any other life pursuit. The habit that devoting yourself to the job you are not into, though you feel like doing other things is priceless. If I develop this habit when I am young, I can avoid wasting so much time.
