Good poetry, at least.
So how to make good poetry?
First of all, it is necessary to understand that any talented writer will read more than he writes. Many writers tend to say, "I don't read because I don't want to be influenced". As a consequence, their poetry is only about themselves; it becomes the expression of an ego that, in all sincerity, no one probably cares about with the exception of a parent or two, and the ones who wrote it.
Poetry should represent the quintessence of life and, in so doing, it should link the poet to the universe entire. A personal experience will be of interest only if it relate to a wider dimension in which each of us can feel participant.
Avoid stereotypes and cliches. So many poems often resemble in their language, styles and figures of speech the poems of other iconic poets. The result is usually a rough copy, highly imperfect, of something that has already been written in a much better fashion by the most talented poets in human history.
Always carry a notebook with you.
The Moleskine brand can be a very good choice, although this is a very personal statement. Although excessively expensive, their lack of frills and unnecessary drawings and decorations help you get straight to the point.
Ideas pop up our mind any moment; we don't want some good inspiration to take flight because we had nothing to write it on when it came up.
Stop being always available!
Cut off a little moment for yourself everyday, one in which you will turn your cell phone off and plunge into your thoughts. This is the only way to be deeply connected with yourself and with the Universe.
Read aloud what you wrote.
Poetry was born to be read aloud and live in front of an audience.
Reading aloud will help you understand what needs to be changed, rephrased, or reworked. Remember, rhythm, patterns, assonances, rhymes, consonances, and other kinds of similar effects can be better "felt" if read aloud.
Sharing with others might definitely give you some useful feedback.
