Memorable poems are rare. To be a really good poem, the poem must be memorable, remarkable in some way. We know they are rare because the complete works of a famous poet will not include all that many of them. Also, poems by great poets before they began to be great are generally no good either. You can't look at a kid's work and predict whether they'll be a good poet later.
But then since most poems are not good, you shouldn't worry about yours. Yours will be bad in possibly interesting ways, and maybe sometimes rise to a level that satisfies you.
