Find out the wrong sentences and correct them.

I think this is a short prose poem, and the language format of the poem is not very strict.

Strictly speaking, the first sentence is a sick sentence: "Life is not all about arrival", because this format is: noun (life) is not verb (arrival). It is similar to "no food" and illogical. An incorrect/illogical sentence

However, as a literary form, poetry is a bit popular now.

If you want to change it, you can change it to: "The meaning of life is not entirely to reach the other side."
