    First off I would like to say superb blog! I had a quick question in which I’d like to ask if you do not mind. I was curious to know how you center yourself and clear your thoughts prior to writing. I have had a hard time clearing my thoughts in getting my thoughts out. I do take pleasure in writing however it just seems like the first 10 to 15 minutes are lost just trying to figure out how to begin. Any ideas or hints? Appreciate it!
