While composing it is very wise to keep an open mind. Try to write just for the purpose of building your skills. Never write just for the comments: if someone likes your poem, fine; if they don't, you just have to work on flaws. Never give up because you've not become a popular poet yet. Write because you enjoy writing; not because you want people to see your works.
'Nuff said.
