I am the new guy

First off I would like to say great blog! I had a quick question which I'd like youtube to avi ask if you don't mind. I was interested to know how you center yourself and clear your head prior to writing. I have had difficulty clearing my mind in getting my ideas out there. I truly do enjoy writing but it just seems like the first 10 to 15 minutes are usually wasted simply just trying to figure out how to begin. Any ideas or tips? Cheers!
