We hate poetry that has a palpable design upon us — and if we do not agree, seems to put its hand in its breeches pocket. Poetry should be great and … - John Keats

Poetry should be great and unobtrusive, a thing which enters into one's soul, and does not startle it or amaze it with itself, but with its subject.

To Sorrow
I bade good-morrow,
And thought to leave her far away behind;
But cheerly, cheerly,
She loves me dearly;
She is so constant to me, and so kind:
I would deceive her
And so leave her,
But ah! she is so constant and so kind.

O Solitude! if I must with thee dwell,
Let it not be among the jumbled heap
Of murky buildings; climb with me the steep, — Nature’s observatory — whence the dell,
Its flowery slopes, its river’s crystal swell,
May seem a span; let me thy vigils keep
’Mongst boughs pavillion’d, where the deer’s swift leap
Startles the wild bee from the fox-glove bell.
But though I’ll gladly trace these scenes with thee,
Yet the sweet converse of an innocent mind,
Whose words are images of thoughts refin’d,
Is my soul’s pleasure; and it sure must be
Almost the highest bliss of human-kind,
When to thy haunts two kindred spirits flee.

Don't be discouraged by a failure. It can be a positive experience. Failure is, in a sense, the highway to success, inasmuch as every discovery of what is false leads us to seek earnestly after what is true, and every fresh experience points out some form of error which we shall afterwards carefully avoid.
