Momentary boredom (for me) seems vital to creativity.

It took me a couple of years to map out the correlation, but having a smartphone seems to dramatically reduce the number of ideas I have.

I go for a walk, wait in line, sit in the train, and am consumed by a horrible feeling of impatient boredom.

The phone alleviates that.

What I realized is that feeling only lasts about 90 seconds and then I start having all sorts of inspired thoughts. The problem is I will use the device to solve the boredom before the creativity circuit engages.
