"There's a guy in my head, and all he wants to do is lay in bed all day long, smoke pot, and watch old movies and cartoons. My life is a series of stratagems, to avoid, and outwit that guy." - Anthony Bourdain
We all have "that guy" somewhere in our head. It may look a bit different from person to person, but the general archetype is universal. You can never silence the voice, you simply learn to resist.
Everything meaningful in life is on the other side of hearing that voice loud and clear and acting in spite of it. Today, and all days, I hope that you outwit "that guy" in your head.
