Enjoy The Journey
Personally, I blog to share my thoughts, my ideas and creations. Being a scrapbooker pretty much requires to have a personal blog in order to share your workshops, participate in different challenges and spread an inspiration thought the craft community. I don't know any of my 700 followers in real life, however, with the help of discussions and comments, many of them I can call friends.
Blogging connects people. By interests, by common experiences and inspiration. Blogging is a true way to express yourself without being judged. You don't have to disclose your personal information and still feel yourself absolutely comfortable to post on any topics.
Be creative. Embrace imperfection. And the main thing is ENJOY THE JOURNEY.
