When ambition ends, happiness begins.
野心消亡之日，正是快乐破茧之时。
If I don't have the wish to be a useful man, I wouldn't be so depressed.
I find I am not happy at all, no matter what I have done.
I am always fearful because I know I am quite incompetent to the work.
What should I do?
Where is my way?
Which is the right direction?
Should I quit on my own initiative?
I don't know, I don't know...
Would you give me some hope, some instruction?
The way to get started is to quit talking and begin doing.
开始做事的方法就是停止空谈，付诸行动。
Stop talking and stop daydreaming.
Do something that is useful.
