With the click of a button my ideas and knowledge can potentially reach millions of people. But I haven't been clicking that button nearly enough.
If I do research, develop a lesson plan, learn a hard lesson in the classroom or put thought into a question, that gives me some amount of value. It enhances my life and the lives of those around me a little bit. But if I share my experiences and my learning with an online community, that value gains a multiplier. A small amount of value multiplied by the number of people who read it and find it useful. If some small fraction of those people develop the idea further and then share their new version, we've got a little exponential growth. Iterated over many thoughts and experiences this can be incredibly impactful.
So day by day I'm building a habit of sharing. This is day two. I may be a lonely math teacher (great post from Dan Meyer) at the moment, but I'm on my way to connecting.
