I go to a local writer's group. Each time I go to a meeting, I feel motivated anew to write more regularly and to make writing a higher priority in my life. Meeting with other writers is encouraging and gives me new ideas. It also gives me a sounding board for some of the ideas I have running around in my head. Moreover, it's fun. I love getting to talk about one of my passions with others who are just as passionate about it
With a houseful of kids, however, blessed as I am, it can be difficult to make it out of the house to meet with other writers. Sometimes, the best avenue available to me is the telephone or e-mail.
Occasionally, I'll call a fellow writer and professional editor and bounce ideas off of her. Not to mention, I always enjoy hearing how her projects are progressing.
Sometimes, I shoot an e-mail off to a fellow author in Austria, an imaginative writer who is also a great sounding board for marketing ideas. Not to mention a person whose unique perspective on things is pretty much always encouraging.
Occasionally, I simply tweet fellow authors. That also can lead to new ideas, end writer's block, and get the gears in my head turning.
Basically, whether it's through e-mail, phone, twitter, or a writers' meeting keeping in touch with others who share my passion keeps me motivated and keeps the new ideas flowing.
