Writing is like anything else you love and cherish - you have to exercise it, give it a chance to grow and mold itself into the best it can be. If your writing is worth it to you, then it's vital to give it the same care and attention of anything else important in your life.
I start a small 1 credit writing workshop this Wednesday that goes through August at my university. In addition, the countdown to my two week writer's workshop has begun. Just 5 days until I get to spend two weeks of incredibly productive creative time around like minds. I can't wait. Some people may think it's weird to use vacation to take a class, but hey - they take vacation for all sorts of things I wouldn't bother going to. Baseball isn't important to me (sorry, Dad).
For my writing, I'm grooming it with some good classes and giving me the chance to actually write. May-June are hell in the finance world, and it's been difficult finding time to write this month; rare for me, but it happens.
Make sure you do what it takes to take care of your writing, whether it be taming it down to a schedule despite its protests or letting it take a sip of whiskey and see what happens.
