What do you mean, "things backfire, never succeed, haste makes waste, start without end"?

Contrary to expectations: it is the starting point and desire of doing things, which is contrary to and inconsistent with the result of doing things;

It is difficult to succeed in the end: it means that the final result is difficult to succeed, indicating that the success rate is extremely low;

Haste makes waste: I just want to speed up, but the faster I think, the slower I do;

Have a beginning and no end: it means that when something is started, it often falls by the wayside, and it is anticlimactic and has no good result.
