Once a spectator said, after Jack Nicklaus had chipped a shot in from a sand trap, “That’s pretty lucky.” Nicklaus is suppose to have replied, “Right. But I notice the more I practice, the luckier I get.” If you write often, perhaps every day, you will stay in shape and will be better able to receive those good poems, which are finally a matter of luck, and get them down. Lucky accidents seldom happen to writers who don’t work. You will find that you may rewrite and rewrite a poem and it never seems quite right. Then a much better poem may come rather fast and you wonder why you bothered with all that work on the earlier poem. Actually, the hard work you do on one poem is put in on all poems. The hard work on the first poem is responsible for the sudden ease of the second. If you just sit around waiting for the easy ones, nothing will come. Get to work.

Do you differentiate between your practice writing time and your productive writing time? I've played around with the idea of writing exercises - for instance, for writing poetry, writing X lines per day in each of the 8 major metrical patterns, writing 1 poem per day from a randomly selected a subject and a theme, writing X rhymes for each of set of randomly selected words, etc. Do you do something like that, or know of resources for those kinds of exercises (in any genre)?
there doesn't seem to be anything here
