Guard your time and your thoughts

Time is the coin of your life. It is the only coin you have, and only you can determine how it will be spent. Be careful lest you let other people spend it for you.

~ Carl Sandburg

It's hard to fight an enemy who has outposts in your head.

Life is not measured by the breaths we take, but by the moments that take our breath away.
