I have a sign in my office that says ‘Say No Nicely’.

And it helps me to focus on what is truly important in my life.

…take life one day at a time, and on the busy days, one hour at a time. Every day pay yourself on the back for the thanks you did well, even if what you did was less than perfect in your eyes – that’s fine too.
