“Cease negative mental chattering.”
If you think a thing is impossible, you'll make it impossible. Pessimism blunts the tools you need to succeed.

The Folly Of Being Comforted http://poetry.poetryx.com/poems/1623/
In The Seven Woods (1904)
Context: One that is ever kind said yesterday:
'Your well-belovéd's hair has threads of grey,
And little shadows come about her eyes;
Time can but make it easier to be wise
Though now it seems impossible, and so
All that you need is patience.'
Heart cries, 'No,
I have not a crumb of comfort, not a grain.
Time can but make her beauty over again:
Because of that great nobleness of hers
The fire that stirs about her, when she stirs,
Burns but more clearly. O she had not these ways
When all the wild summer was in her gaze.'
O heart! O heart! if she'd but turn her head,
You'd know the folly of being comforted.
