perspectives 这首诗的感想?

One cannnot change the outside environment, it is the world that changes people.
when one is resolved to change sth,it means he himself will remain the same,then he is a idealist;when one can live with the unhappy reality,he has changed a lot and finally gains his spiritual growth, now he is a realist.
Maybe sb will argue that it is deteriorating to bandon one's youthful dream to became a cold and indifferent adult,however ,this is just what the world always go.Naive ideas more often than not brings painful experience,while an adult's perspectives can make one wise.
What does growth mean?It is the process from remaining the same to changing according to the changed.
So the theme is change and growth.
