The poem uses the refrain on 'to live' to show the insistence of the poet on will to life and to keep going on despite hardships that might pull her down.
The hopefulness of the poem is also accentuated with this refrain on 'to live' which reaffirms life. What lies ahead in life is presented as life and what is behind is what should be moved on from.
<u>Hence, it becomes a continuous process 'to live' and thus the line serves as a refrain.</u>
When you get on a rollercoaster, closing your eyes, not knowing when the steep part of the coaster will hit. Describe your emotions and then also describe how bad the impact the drop was to your insides.
