"Tool?" you say.
"Yes, tool." Anything that has the ability to put me in a peaceful, content mindset and helps me to tap into my creative side unimpeded is a tool.
Guinness. I only need one. I'm not a lush. One "Guinness glass" of black and creamy comfort. What do you enjoy as you write?
If you want to read more about my affinity for Guinness, I included a link of a vintage blog of mine. Just click the glass of Guinness.
