First of all I want to say terrific blog ! I had a quick question that I’d like to ask if you don’t mind. I was interested to know how you center yourself and clear your thoughts before writing. I’ve had a hard time clearing my mind in getting my thoughts out. I do enjoy writing but it just seems like the first 10 to 15 minutes are usually wasted just trying to figure out how to begin. Any recommendations or tips ?
Cheers !
