  1. First off I would like to say wonderful blog!
    I had a quick question that I’d like to ask if you don’t
    mind. I was interested to find out how you center yourself and clear your
    mind prior to writing. I have had a tough time clearing my thoughts in getting
    my thoughts out there. I do enjoy writing but it just seems like the first 10 to 15 minutes tend to be wasted just trying to figure out how to begin. Any
    ideas or hints? Cheers!

  2. Can I simply say what a relief to find somebody who actually understands what they are discussing online.
    You certainly realize how to bring a problem to light and make it
    important. More people must check this out and understand
    this side of your story. I can’t believe you aren’t more popular since you most certainly have
    the gift.
