The best authors out there always say the way to become a better writer is to write. Write all the time. Write on a schedule. Set aside the time every day to write, even if you don't have it available. With our busy lives and families and work and kids and well, whatever else, there just isn't enough time. That 25th hour of the day isn't available, and even if it were, you probably wouldn't want to spend it writing when that new episode of your favorite television show is on.
But that's the thing. There's always time to write. We have a finite amount of time every day, but yet we always find time to do the most pressing items on the list, and we find time to squeeze in the stuff we absolutely have to waste our time on too, no matter if they're important or not.
That's where writing comes in. For a writer, writing should be a part of the stuff we simply cannot do without. It's easy to vege out in front of the television, or waste time on teh interwebz. It's hard to write. It takes time, dedication, research, and just plain grinding through those tough parts where the whole thing seems to bog down hopelessly.
But the advice - write, write, write - holds true. I've been writing since the 80's, and in between then and now, I've been some pretty interesting places. I've been everywhere from tropical paradises with all sorts of distractions, to war zones with a completely different set of distractions. Everywhere I've been, I've written. And I've found it easiest to write when I was horribly busy.
For me, if I have little to do, I put things off. I go into slacker mode, and my writing suffers. When I'm busy, I transfer that energy into my writing and somehow find time to put in the time to finish at least a few pages every day. It's not easy channeling any energy you have left into your novel after an 18-hour workday. It's not easy after eight hours in a cushy office. But if you force yourself into the habit of writing, especially when you are the busiest, you'll find it easier to write. In fact, I'd wager you'll find yourself looking forward to writing, because it becomes an escape from the busyness of your hectic schedule.
