Next time you wonder: is this good, or any other form of that thought, direct your attention to it. Don’t just recognize the thought process, but take the seat of an outside observer and look at what is happening in front of you.
What is good is rarely black or white. And yet we spend our day reacting instinctively to this question with almost every step we take.
Maybe the passing thought of wondering is an invitation to pay more attention.
And since the brush is in your hand already, you might as well discover all the new colors that suddenly became available for your next stroke of inspiration.
