Why can't my brain turn off??

So it is 2:20am and I can't sleep. I went to bed. Slept for a few hours and now up again. My brain is just going about photography this and photography that. I hate that. I need to go to bed. I have to do hair tomorrow for a wedding and then stay and work with Serendipity. So it is looking like a 12 hour day tomorrow. And I sit here typing away at my compurter. Look. I even spelled "computer" wrong. And too lazy to backspace and fix it. Would rather just keep typing.........Wow am I just feeling overwhelmed! Last night I went to a get together for photogs "hosted" by Becker who runs the [b]school. I am not too familiar with his work which I guess he is AMAZING and so many people were there last night to see him. But he was soooo down to earth and funny! And he drinks diet cokes like they are going out of style! It was so cool to just mingle and meet so many people. DaBomb.com kind of people! I, being the complete newbie felt so surprisingly comfortable. And now I can't sleep. Cause I was sitting there listening to all the conversations and taking in what everybody was saying and just...... wow. There is so much. But I love it. My husband nailed it on the head when he said I loved photography so much because I never will stop learning something. I always like to be challenged. Whether it is shooting techniques, computer sh*t (as you can tell my most frustrating part), business models, networking, marketing, working with clients, yada yada and the list goes on. I just wish my brain would turn off so I can sleep ...............so lets try this again............Good night now..........
