Fall in love!
That’s all I can say for now and all the advice I can give, fall in love!
With what, with whom, or how you do it, well, that doesn’t matter. What matters is that you fall in love.
After you have done that (the falling in love part), everything else is unimportant.
Yes, there are things like:
The first poem you write it has to gush out of your soul like a stream of water that just found its way from a deep cave;  turbulent, fast, and impure at the same time!
It has to contain every piece of your soul in it, cause that’s what poetry really is, your soul morphed into a different thing, morphed into a black ink that slithers on a white page, imprinting yourself on it.
But these are details, only details that you will be doing unconsciously, whether you like it or not!
The first poem you will be writing won’t be smart; but it doesn’t have to be smart, structured, or even good!
What it needs to be, is YOU! You, and no one else! No Frost or Bukowski; No Poe or Neruda; No Whitman or Baudelaire; No Keats or Yeats… or anything of their kind.
Cause trust me, if you are able to keep being yourself while writing it, your first poem will be better than any other poem written by any of them, and whoever says otherwise, is a liar! (and probably hates you)
Your first poem will contain all the hate, joy, pain, greed and fear you’ve ever felt, and yet, it will turn out to be the most beautiful thing you’ve ever did; the most beautiful thing you’ve ever had.
But, enough of my nonsense;
Start writing, start falling…
