阅读理解。 One day the employees of a large company in St Louis, Missouri returned from their lunch break and were greeted with a sign on the front door. The sign said: 'Yesterday the person who has been hindering (阻碍) your growth in this company passed away. We invite you to join the funeral (葬礼) in the room that has been prepared in the gym.' At first everyone was sad to hear that one of their colleagues had died, but after a while they started getting curious about who this person might be. The excitement grew as the employees arrived at the gym to pay their last respects. Everyone wondered: 'Who is this person that was hindering my progress? Well, at least he's no longer here.' One by one the employees got closer to the coffin (棺材) and when they looked inside it they became speechless. They stood over the coffin, shocked and in silence, as if someone had touched the deepest part of their soul. There was a mirror inside the coffin. Everyone who looked inside it could see himself. There was also a sign next to the mirror that said: 'There is only one person who can set limits to your growth: it is YOU.' You are the only person who can revolutionize (彻底改变) your life. You are the only person who can influence your happiness, your realization and your success. You are the only person who can help yourself. Your life does not change when your family changes, when your friends change, when your boss changes, and when your company changes. Your life changes when you change, when you go beyond your limiting beliefs, when you realize that you are the only one responsible for your life. 1.
