There is nothing like having a grand idea. I remember the first time I wanted to do a full day conference, even though had never done a conference before. I had thrown a few events, but nothing like orchestrating 25 speakers, getting people to attend, finding a place to host it and finding sponsors to pay for the expenses. But I did it. Not with one action, but with a series of very small actions. From sending emails, to creating outlines and brainstorming how things were to be.
It's like that with blogging. It's not as easy as just having a big idea then doing that one thing that makes a blog great. It's doing all the small things like posting, tweeting, connecting with the community that make a blog great.
So when you're getting caught up in the motions, remember that you're working on something special, and these little things will make your efforts into something truly wonderful.
