Personal Branding? Sounds Painful

So I have been reading the posts about personal branding. I think I get it. No really I think I do! But I don't know if it's something that you can go out and "create". Everybody is talking about it like we all need to hurry up and brand ourselves! ouch? But that just seems impossible when you don't have a direction.

I mean, I want to blog. I want to write inteligent entries that make people think or at least respond to. But my life and experiences are all a mish mash, like scrapple. Maybe that's a good thing though because I can appeal to many different types of people... but then how do you get people to follow your blog if everything is different? I guess that's the point of a 'personal brand'.

How do you bring all the mishmash together...
My degree in psychology - I have a fascination with law and psych (forensic psychology).
My work - I currently work in the mental health field and with the foster care system.
My volunteering - I volunteer with CASA, aka: i'm a guardian ad litem. (spelled right?)
I love books
I love to cook
I love to do things outside.

But what I really want to do is build a content website for profit and learn calligraphy.

I have a lot of thoughts on the foster care system and psychology, and I have recipes to share and pictures of my food, I'd love to share the books I'm reading...

But all that probably wouldn't do much for my artistic calligraphy-based website. They are completely unrelated. But I want to write about it all.
So how do I bring it all together in a personal brand?

I don't know. But I am very much an individual, not afraid of being myself and letting my true colors shine through, so to speak. So I have faith that eventually it will all come together and that lightbulb moment will happen. Maybe the brand just comes about on it's own. You know, I've been reading several different people's blogs and what I've found is that the ones I like usually have topics that I enjoy even if the main point of their blog (ie: their career path) is completely uninteresting to me. They blog about other things too.

Until then I just have to keep learning and growing and writing because after all that's the whole point of a blog, right? It's my personal path to self discovery, as Penelope says.

Writing seems to help me sort through my thoughts. Does it work for you as well? Why do you blog? Do you feel like you have created a 'personal brand'?
