In the picture we can see a man, who is not realistic, lying there thinking good luck might happen to him one day.

However, an old saying goes: No pains, no gains. We all know that chances usually look upon those with favor who are ready to act. But in our society today, there are still some people living in a world of fantasy without working hard. Of course everyone wants to succeed and have a better life. We can’t imagine how a man can succeed if he never tries. So let’s try hard no matter how many difficulties and failures we will meet on the way. Only by working in a down-to-earth manner and advancing step by step, will chance and success finally come to us.
