Proverbs and saying for not achieving a specific situation (or objective)? I am looking for a set of Chinese 成语 and 俗语 describing ways in which a desired situation may not be achieved.

For instance, like the following two:

欲速则不达

东施效颦

Any others?

Where can I find a complete list?

Thanks.
I think there are too many 俗語, 諺語 to list.
Here are few similar 成語 for you

揠苗助長 = 欲速則不達
適得其反 to the end, get opposite effect
事與願違 nothing comes out as planned
