I want to study poetry, what would you advice me?

Read as much as you can.

Read different types of material, not just poetry. It widens knowledge, introduces new words and experiences.  

So read material that is fact and fiction.  

Read the work of different writers and poets.  

Read the work of national and international poets/writers.

Tune into your strength and the kind of poetry that interests you,

Enjoy the process of thinking of ideas to write about.  

Write ideas down where ever you are, ideas come at the strangest of times or places. 

Be willing to rework material and keep at it.
