A strange thought came out of my head on my way home yesterday. Why did I want to be a manual worker with so much knowledge? Let me think it over. If I have much knowledge, I may feel tired easily when I’m doing something, especially some manual work. However, if I’m a mental laborer with little knowledge, my head may not run agilely – – I won’t feel unhappy easily, either. Because there’s little knowledge in my head and I may not feel the feelings quickly. So the best choice may be that I don’t have the ability to match the work very well. I should give me some spare time for my life. Did you understand it? A manual worker with more knowledge, or a mental laborer with better physical strength, they match perfectly. They look like a staggered beauty in our lives.
