Hair Funk

Lately I've been feeling like I'm in a hair funk.  I'm not really sure what I want to do with it.  Sometimes I love it long and other times I'm ready to chop it all off.  This is approximately what I currently have:

Which, if I motivated myself, I could in theory use to create amazing hairstyles like this:

And if I really decided I needed a change, I could just keep it long and go blonde:

I love the idea of being able to style my hair so diversely, but the fact is, I usually just throw it back in a pony tail or up in a bun as I run out the door.  So the other option is to chop it all off again.  It's been a while since I've had my hair short and I love the shock effect of such a major change.  I find short hair to be flattering on me, and it won't get in the way as much as my long hair does, but it does also limit my styling options...

 

What do you think I should do???
