I am writing a poem. Can someone please give me some suggestions on how to imporove the poem, especially line 5. Also, I want to use some sound devices in the poem. Any ideas? Here is the poem:

Education
You are light that lightens up our lives
You are as vast as sea that cannot see the end
You are so significant and invaluable that you claim our attention
We value you, we demand you, we need you, no matter what ages we are
And the light ignited by you will stay in our mind
Without you, our light will die out.

Is "You are light that lightens up our lives" an example of metaphor?
Is "You are as vast as sea " an example of simile?
Also, is there a sound device used in "We value you, we demand you, we need you" ?

Thank you!

Is "You are light that lightens up our lives" an example of metaphor? yes

Is "You are as vast as sea " an example of simile? yes

Also, is there a sound device used in "We value you, we demand you, we need you" ? yes, repetition, almost rhyme

And more of the same metaphor in lines 5 and 6. Nice.

To improve the poem, especially line 5, you can try to vary the sentence structure and use more vivid language. Here's a suggestion:

Education,
You are the radiant beacon that illuminates our lives,
A boundless expanse, the endless abyss of knowledge,
So profound and invaluable, capturing our undivided attention,
Regardless of our age, we cherish you, rely on you, yearn for you,
And the flame ignited by your touch shall forever reside in our minds,
In your absence, our brilliance shall wane and wither away.

Now, let's address your questions about literary devices:

- "You are light that lightens up our lives" is an example of a metaphor as it directly compares education to light.
- "You are as vast as sea" is indeed an example of a simile as it uses "as" to establish the comparison between education and the vastness of the sea.
- In the line "We value you, we demand you, we need you," there is a repetition of the "you" sound, which makes it an example of consonance, a type of sound device that involves the repetition of consonant sounds within words or phrases.

Hope this helps! Let me know if you have any further questions.
