Don't criticize what you can't understand.
不懂的，不要随意批判。
From Bob Dylan.
Don't criticize what you can't understand, because you never walked in that man's shoes.
Don't point your finger and criticize, because you have three fingers pointing right back at you.
But that's not true in most cases, even though others don't understand what you have gone through, they still can voice their opinions, you know, and those opinions, pertinent or not, all can serve as good ways for us to improve our performance.
Cease to struggle and you cease to live.
生命不止，奋斗不息。
When I was young, I had ever written a composition about my ideal and my dreams, now it seems that I am getting farther and farther away from them.
In such a materialistic age, most of us are busy in pursuing wealth, and it has become the most important thing in measuring whehter a man is successful or not.
I don't have money, I even can't afford a house without the help from my parents.
Sometimes I really want to give up, I really want to stop making any efforts to fight against my tragic fate.
But cease to struggle, and we would cease to live, so I won't give up till my last gasp.
