I ran across a few of my favorite quotations. This was once kind of a motto for me. I am considering adopting it again. It is by Edwin Markham, also author of The Man with the Hoe, and other poems.
For all your days prepare,
and meet them ever alike.
When you are the anvil bear,
when you are the hammer, strike.
It gives me the strength to either hold up to challenges, or to forcefully push through at opportunities.
I would like to hear some of your motivating quotations!
