Attentiveness is occurring right now as I sit here writing this; as my eyes scan the screen I'm able to simultaneously notice the sound of my fingers on the keyboard, the television in the background, and the sound of traffic outside. I'm also aware of what's going on ‘internally' and can notice thoughts arising by themselves, the way I mentally verbalize these words as I edit this paragraph and consider whether it's an accurate description or not; a reflection based on the way that I understand the words I'm using and whether or not others will understand them in the same way. All of this can be observed occurring without effort, but the simplicity of attentiveness is what makes it difficult for some to perceive.
