I sit in front of this small iPad screen, my brain taking in and interpreting the light and shade on that screen. Sometimes the light and shade forms words, sometimes images. These words or images convey ideas. I decide what those ideas mean, whether they matter to me, and what I am going to do with them. Sometimes I sense that they have changed me. Sometimes they have changed me in a small way and sometimes in a big way. No matter in how small a way - they have changed me. They have either made me think differently, or to think more confidently what I thought before. Sometimes I want to offer the opportunity of this change to others and share the light and shade on my screen with them through the miracle of the internet. Sometimes they change and sometimes they don't.
