How to write good poetry.

Revision

Another good aspect to talk about is your revision.

I saw a quote once by someone called @Jhorsfall which says, 'Writing is a skill and revision is a talent.' when you're done writing, check out your spellings, punctuations, lines and structure. Writing a good poem that contains spelling errors is a no-no; it reduces the poem's beauty and irks the reader. There are articles on the internet that teaches the use of punctuations and grammar, try to read it; see it as an investment in your poetry career.

So keep this at the back of your mind; before releasing that poem of yours, always go over it till you're satisfied.
