I said in a post just last month that my mottos are usually given to me and I have yet to dream one up on my own. It happened this afternoon for the Des Moines marathon this weekend:
Every step is a victory.
Someone simply says something to me and it hits me! This could be a motto for many people, so feel free to incorporate it for yourself if it hits you in the heart. I hope it hits you in the heart if it's what your heart needs.
