Question: What is worth desiring from the world when everything is impermanent ?

I can't even desire Nirvana , because I never get it. [Here](https://suttacentral.net/en/mn1) it states that I can not say Nibbana as mine or me or myself( I can not say I am in state of Nibbana and I can not say Nibbana as mine):

> 
> “He directly knows Nibbāna as Nibbāna. Having directly known Nibbāna
>  as Nibbāna, he should not conceive himself as Nibbāna, he should not
>  conceive himself in Nibbāna, he should not conceive himself apart from
>  Nibbāna, he should not conceive Nibbāna to be ‘mine,’ he should not
>  delight in Nibbāna. Why is that? Because he must fully understand it,
>  I say.

( I am asking this question to understand the depths of knowledge... I am trying not to take delight in asking such questions.Buddha says one should not even take delight in Nibbana.)

Answer: 
You can want to be strong instead of weak. You can want to be a master instead of victim of circumstances. You can want to learn to control your mind. You can want to help others feel less suffering, in both ways (external and internal help). You can want to know the truth from the myths.

This world is a dream and everything here is like a phantom, but you can use it as gym to practice. Even if impermanent, this is good exercise.
Isn't a paradox to say everything is impermanent? Doesn't the view "everything is impermanent" remain in your mind until you die? So, there you have it, you can have something permanent until you die.

You can also permanently (until you die) abstain from killing, abstain from taking what is not given, avoid sexual misconduct, abstain from false speech and refrain from intoxicating drinks and drugs. These precepts wouldn't have been given if it not possible to maintain them permanently. So, if you want these you have them permanently until you die.

But don't wish to be strong, rich or healthy permanently (until you die) that may not happen.

Edit: I misunderstood you, I thought you are asking permanence in this life, if you are looking for inherently permanent to be declared before you follow the five precept and the Nobel eightfold then the permanence you are looking is not declared by The Tathagata.
