What do I know?

I spent the past two days absorbing a lot of amazing information. A lot of it, I could say that I have heard before.... But, do I know it? How do I know if I already know something, concepts, ideas.... Does anyone know it? Even the trainer? I mean, they are concepts right? If I say I know it... I miss it. A lot of it I have heard before... Great! Am I living it in my life? And the concepts I heard that are new to me, what good is it if I don't practice it? My commitment to myself is to continue to learn, be open and be in action... That's the only way I know I'm moving forward.
