Every morning, I'll say a brief prayer as I leave for work.
I pray for my parents and my three sisters.
I pray that today will be a better day than yesterday,
I pray for my every action and my every word will be out of necessity and that it leads to a greater purpose.
If today was meant to be a bad day for me, I pray that I am able to accept with humility and that I'll find the underlying wisdom.
I pray that I'm always reminded of what I do not lack.
I pray that I am content with what I now hold.
I pray that I am able to firmly hold on to what really matters, and am able to easily let go of what is not (though at times I have difficulty to distinguish between the two)
I pray that my every waking moment makes me a better man,
If today was meant to be my last, I pray that I'll be able to say that I've lived a full life, and am prepared to move on to the next.
P.S. I do realize that realistically, saying all these things aren't exactly what you'd call "a brief prayer", but I suppose if you do it every morning, one would know them in a heartbeat.
