    First off I would like to say great blog! I had a quick question in which I’d like to ask
    if you do not mind. I was interested to know how you center
    yourself and clear your mind prior to writing. I have had a difficult time clearing my mind in getting my thoughts out.

    I do enjoy writing however it just seems like the first 10 to 15 minutes
    are generally lost just trying to figure out how to begin. Any ideas or hints?
    Many thanks!
