Lecturing to one self..?

I am lecturing. In actual fact I am lecturing to myself, by myself, for myself. The self in me is supposed to be everything. I am the one who is knowledgeable. Those who listened shall picked up something that comes from myself. But where does the ideas in my writing comes from? Is it a self-generated piece of activity? Hanya Allah Sahaja Yang Maha Mengetahui.
