Blogging is great for your business, and it can be great for you too. But not if you are paying so much attention to what your competition is doing that you get all stressed out about it.
I belong to a bunch of blogging groups on Facebook, and I can tell you that there are some really amazing blogs there. And I’ve had some serious cases of blog envy over the years. But if I spent all my time stressing about what they do better than me (and there’s a lot of that), I’d never get anything done on my own sites.
