I used to feel like this once

From an interview with Marnie Stern:

"That was when the biggest creative surge of my life happened, and nothing like that has ever happened since. My mind was open. Open to anything and everything, and that was the best two years of my whole life... I felt inspiration everywhere. Everywhere! Everything I heard, I was like, 'That was for me.' 'That was for me.' I was so positive and forward and yes, yes, yes. You know, and it was a great, great time... It was really terrific. That's when I got the idea that I could do anything. There were no boundaries or rules or limitations..."
