What running teaches you about life

I came across this article titled, "Things that running teaches you about life". Don't skip it, it's really quite good.

.....Would you be asking yourself “should I run today?” if a blood hungry lion came running after you from a little distance? Even if you damn well knew that you could never outrun a lion you’d run for your life. When we rationalize things we tend to cut ourselves slack and lean towards the option with the least effort. It’s the primal urge to conserve energy when we really need it. The problem is modern life rarely confronts us with moments when we “really need that energy” and when it does we’re too out of shape and uncoordinated to do anything of use.

I liked this bit about boundaries:

All training reaches a plateau, not just running. Even intellectual pursuits reach a point of monotony. How do world-class pianists train? By playing scales and classics over and over again. The only way to improve and not stagnate is to push the boundaries and stretch them without snapping or breaking them. Remember, there are always two boundaries: the ones we set and the ones set for us (you can only play the piano so hard without going insane). Your mission is to find the boundaries set for yourself and challenging them without crossing your absolute threshold.
