The poem Psalm of Life (see the image below) is morally uplifting and sentimental for the tone of the poetry is convincing the reader to live life to the fullest.
As I will compare it to my life philosophy which is to do everything with great passion because we cannot do big things, we can only do small things with great love... I think, they are somehow similar because Longfellow said, "Let us, then be up and doing, with a heart for any fate; Still achieving and pursuing, Learn to labor and to wait."
