Memento Mori, it is a reminder that your time is limited and that one day you too will die. Not so much a motivational quote as it is a statement of fact. "Without Fear You Are Free", how many opportunities have been missed to date in your life because of fear?  Do that thing, take that chance... better to go balls out for whatever time you have left than allow fear to keep you hostage. In the final moments of your life you do not wish to find yourself full of regret. You are going to die some day. What will you do with the time you have left?
