Project Management can be tough and draining, many a times. For times like these, i find the book Meditations by Marcus Auerilis to be inspiring and motivating. Here is a quote from the book.
"No carelessness in your actions. No confusion in your words. No imprecision in your thoughts. No retreating into your own soul, or even trying to escape it. No overactivity.
They kill you, cut you with knives, shower you with curses. And that somehow cuts your mind off from clearness, and sanity and self-control and justice?
A man standing by a spring of clear, sweet water and cursing it. While the fresh water keeps on bubbling up. He can shovel mud into it, or dung, and the stream will carry it away, wash itself clean, remain unstained.
To have that. Not a cistern, but a perpetual spring.
How? by working to win your freedom. Hour by hour. Through practice, honesty and humility."
