How I did it: I figured out what I wanted my blog to be about, I worked on the content, the writing and the pictures. I spent time looking around the blogosphere for inspiration and community. I commented thoughtfully on other people's blogs. I joined challenges and groups of like minded folk. I wrote regularly and/or everyday. I had fun.
Lessons & tips: Figure out what you have to give to the world and share it. Don't be mean, be supportive. Make friends. Find people who are doing what you want to do and follow their links to other people. Offer inspiration and education and beauty and love. Be yourself. Work on both the written aspect and the visual aspect, because you want it to be both well written and visually appealing.
