A couple weeks ago I decided to take a run on a gravel path in Central Park. As I ran, about every couple hundred feet I would get a small pebble in my shoe. Every time this happened I would stop, balance on one leg, and shake the small stone out of my shoe. Then I would continue running. This happened about 5 times, and each time I would get a bit more annoyed. These small rocks were ruining what should’ve been a nice time. So, seeing as I could not fix the rock problem, I decided to just ignore it. After a little while I totally forgot about the rocks and discomfort and contently finished my run.
There will always be a rock in your shoe, so you better get used to it.
