The quality of amateur poetry can vary widely, and it's not accurate to make a blanket statement that all amateur poetry lacks substance. Just like in any form of art, there are both well-crafted and impactful works as well as those that may seem shallow or lacking in depth.
Amateur poets are typically individuals who are exploring their creativity and expressing their emotions through poetry without formal training or experience. Some amateur poets may indeed focus more on style and aesthetics rather than delving deep into complex themes or subjects. They might prioritize the form, rhyme, and rhythm of their poems without necessarily developing substantial ideas.
On the other hand, there are amateur poets who genuinely pour their emotions, thoughts, and personal experiences into their work, leading to poems that carry significant substance. While they may not have the same level of technical skill or literary finesse as professional poets, their poems can still resonate with readers on a deep emotional level.
Ultimately, poetry, like any art form, is subjective. What one person finds lacking in substance, another might see as deeply meaningful and impactful. It's also worth noting that the distinction between amateur and professional can be blurred, as many renowned poets began their journey as amateurs.
What matters most in poetry is the connection it establishes with its audience. Even amateur poetry can hold great value and meaning for the poet and those who appreciate their work. Whether a poem is considered successful or not is a matter of individual taste and the emotional response it evokes in readers.
