How do you know if your poems are good or not?

[Fathima]

I mean, I've shared a few of my poems to people. Some say they love it or really like it, and others have called it lame or laughed at it.

I just started writing, but I have no clue if my poems are any good or if they even make sense. I've always wanted to write poetry, but never knew where to begin, and I do lack a bit of confidence in writing. I do realize that a lot of it is based on personal preference and opinions. But is there really any way of knowing if you've written a good piece of work?

Thank you.
