Whether you’ve got a specific goal to reach or just want to lead a healthier life, starting a blog could help you succeed. Marie Ainey, who lives in Toronto, has had her fitness blog "Mouseroo's Mumblings" since November 2006, and uses it to record her attempts to stay at her goal weight. "I started the blog because it was a great way to put out how I was feeling, get feedback and connect with people who identified with what I was going through," she says.
