How to treat the sentence "hope for the best, try your best and prepare for the worst"?

This sentence gives the impression that:

1. One must have hope in one's life, and then keep working hard, but not everything is 100% successful. For the failure of things, one should have the ability to resist blows. If things fail, they will never recover.

For example, if you want to have hope in your studies and keep working hard, you can be admitted to colleges and universities, but not every effort can be successful. If you fail in the list, don't be depressed. You can change your life's destiny by repeating reading or other means.

There must be hope in everything, because only hope can make efforts. However, prepare for the worst, that is, after you have done this, you should think about the result and prepare yourself for good or bad.

Extended data:

The practical significance of this sentence:

1. Before you do something, you need to be full of hope and try your best to finish it.

2. After finishing one thing, don't expect too much and add pressure to yourself. Many times, as long as we try our best, the result is not that important, and sometimes the process is more important than the result.
