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):

( 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: 
Nibbana is not of the world. Nibbana is experienced by the mind & not by the self. In Buddhism, the 'self' is merely a thought (SN 22.81).

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.
