"A bird does not change its feather because the weather is bad"

I received this Nigerian proverb about persistence today and found myself thinking just how timely it was. I have had a bit of a backslide motivation wise, I am not sure if its because I am so so tired, or if its just one of those things. My nutrition has been horrible this week. I decided today to force myself out for a 45 minute run, something positive for my soul.
