It’s been one of those days. You are creatively blocked. No juices flowing. No ideas. Your mind spins in an endless loop, going nowhere. The canvas stays blank. The strings on your guitar sound flat. The cursor blinks at you with a sneer.

This is what creative paralysis feels like. Being locked inside your skull, unable to move.

I want to suggest an age old solution to your creative block: go on a walk.

There’s an old saying, attributed to the Greek philosopher Diogenes the Cynic: solvitur ambulando. “It is solved by walking.”

We all know walking is good for us. If you spend your days at a desk, you’ve been told to stand more, to stretch, to “get in your steps.” But walking isn’t just exercise. It is fuel for creativity.

In the world of creativity, there's something called the Creative Wind Tunnel. Ryan Tedder, the songwriter behind hits for artists like Beyoncé, Adele, and his band OneRepublic, uses this term to describe the phenomenon when creators get tunnel vision and start thinking their work is perfect, losing touch with reality.

When you're in the Creative Wind Tunnel, you can’t see your work’s flaws because you’re too caught up in it. This can stop you from making something truly great.

Trust the process. Even in the in-between time. Even when you can’t see the finish line.

After the success of their 1997 album, “OK Computer,” British rock band Radiohead faced immense pressure to produce another landmark effort.

Lead singer and songwriter Thom Yorke was burnt out from the intense tour and promotional schedule they had been keeping.

But critics and fans wanted more. More melodic rock. More angsty lyrics. More of the same. They wanted OK Computer, Vol. 2. Imitators of the Radiohead sound were starting to sprout up. Other bands, such as Coldplay, would go on to build huge careers making their own versions of OK Computer, Vol. 2.

But instead of doing the expected, Radiohead released Kid A, a surprising, confusing and divisive album that took the band in a starkly different direction.
