Another short tip. Don't sit around and wait to become motivated or inspired to work. If you want to be a pro, you don't wait until you feel like working. Back when I was teaching, I couldn't call in and say to my dean, "I'm not coming in today. I just don't feel inspired." He would have suggested that if I didn't get inspired quickly, I would have many more days that I didn't have to show up to work.
Discipline is more important than inspiration. Many times I find that my "inspiration" or "motivation" doesn't appear until after I've been writing for some time and not before.
Set a schedule for writing. It doesn't have to be a long time. It can be ten-minutes a day if that's all the time you have. It can be at different types during the day if you work a variable shift, but put it down in your calendar just like an appointment and treat it with as much respect as you have for a business meeting or a family outing.
Be realistic. If you can't do an hour a day, don't set that as your goal. It is better to do 10 minutes a day every day than an hour once every ten days.
There was a sign up at an insurance agency where I worked breifly many years ago. It read, "Plan your Work, then Work your Plan." Set up a plan to write on a regular basis and even if you just type random words, do so. The muse will visit more often, when you create a nice work environment for her daily.
