'I see' and 'you are surprised' are two separate clauses -- so they should be connected by 'that'

But in my soul

I'm a poet

Don't forget the article! Use 'a' when you are introducing something for the first time in a text and use 'the' when you want to refer to the same thing again later.

So I would like to present you

My very good and little poem

You can put 'and' here and it would be grammatically correct -- but it is correct without 'and' as well

All children want to be more older

'Older' is already a comparative here, meaning that it already express the meaning of 'more' -- 'more' is not necessary here

And I'm notno exeption exception

You could either say 'I'm not an exception' or 'I'm no exception' -- the first one being more formal and grammatically correct and the second one being more similar to daily life language

But what means is growing up for me?

In a wh-question, the formation is always ' What do/does ...' if there is a verb in the rest of the sentence or 'What is/are...' otherwise.

In this case, 'growing up' is a gerund so it acts as a noun instead of verb, so we use the formation of 'what is..'

Similarly, we can say ' What does it mean to grow up for me?' because now 'mean' is not a gerund, so it acts as a verb.

We cannot say ' What means growing up for me' because we have to use the formation of 'What do/does' or 'What is/are'.

It's my private position

This phrase is grammatically correct but i'm not quite sure what it means. Perhaps you could explain me more and I could help you to find a better alternative!

I hope this is helpful for you!

check my poem it isn't the end

Very good, clear and easy to read.
