Final answer:
Langston Hughes wrote the poem 'Dreams,' which emphasizes the significance of holding on to dreams by comparing a life without them to a bird that cannot fly.
Step-by-step explanation:
The lines "Hold fast to dreams/For if dreams die/Life is a broken winged bird/That cannot fly" were written by the poet Langston Hughes. They come from a poem titled 'Dreams', which reflects on the importance of dreams and ambitions in life.
