Darren Rowse at ProBlogger.net has asked other bloggers to participate in a group writing project on the habits of effective bloggers. At first I thought this wouldn't be appropriate for this site, but then I realized that the habits of an effective blogger are often the same as the habits of anyone who is effective in other areas.
Stay focused. Before you begin a blog or any long-term commitment, you develop a plan and goals for it. But life happens, so as time goes on it is easy to wander away from these plans. If you do you will be breaking the commitment you have made to your readers and to yourself. To keep this from happening, at least once a week review your plans and goals for each of your projects, and compare what you have done in the past week to what you have planned. This frequent review allows easy course correction.
Stay balanced. Your vocation or avocation, including your blog, isn't your entire life. You have relationships. You have other areas of life. To keep each of these fresh you need to make sure you spend time and energy on all of them. This doesn't mean that you won't have periods of focus only on one thing, but it does mean that these periods of high focus can't become habitual. No one can effectively do the same thing day after day and hour after hour while expecting quality results. Take breaks during your workday. Take time for those you love. Take a vacation for re-creation. These breaks will only make you more effective.
Emulate your role models, but don't imitate them. All of us have role models, people who influence our beliefs, our actions, and our style. This is good. This is how we learn. Regularly study the work of other people in your field. Learn from people who's work you admire. But you have to take what you learn from what you read and what you see and mold it into something new. Imitation demeans you and your readers, while emulation will teach you how to free your own voice.
Use habit. Don't let it use you. Your daily routine is the framework you use to live a creative life, but it is a framework, not your life itself. Don't let your habits become ruts. They are there to serve you, to free you to focus on creation. Periodically examine your work to make sure you aren't just working out of routine, but are actually putting conscious thought into what you are doing. It will show in your writing. It will show in your readers.
