Why don't we write?

It's becoming increasingly important that we write. Not only does it help us redefine our thoughts, the internet makes it the most potent form of expression.

Yet, most of us don't (myself included). 

So, what stops us from writing? A few candidates:

  • I don't know what to write about
  • Who'd read this anyway?
  • This sounds stupid. Is this worthy of being written?

I know there are philosophical rebuttals to each of the above points. For instance: "You should write for your own sake and not for an audience." However, I'm not convinced that the answer lies there. I wonder if the tools we use for writing can help us overcome these.
