What kind of psychology does the three crowns represent Newton?

He also wrote a poem called "Three Crowns" for this purpose, expressing his attitude of being willing to bear the pain in order to realize the ideal of devoting himself to science:

Oh, the worldly crown, I despise it and regard it as the soil under my feet.

It is heavy, and in the end it is just an emptiness.

But now I am happy to welcome the crown of thorns.

Although it hurts, it tastes sweet;

I saw the crown of glory in front of me,

It is full of happiness and eternity.
