Some thoughts

“Dubito, ergo cogito, ergo sum.”
René Descartes

“We are just an advanced breed of monkeys” on a minor planet of a very average star. But we can understand the universe. That makes us something very special.”
Stephen Hawking

“Like a Shakespearean sonnet that captures the very essence of love, or a painting that brings out the beauty of the human form that is far more than just skin deep, Euler’s equation reaches down into the very depths of existence.”
Keith Devlin, as quoted in Dr. Eulers Fabulous Formula, 2006

“Over the past 25-35 years however; the number of projects in the workplace has skyrocketed.  Projects of all types and sizes are now the way that organizations accomplish work that involve development and change.  At the same time, a new breed of project manager has emerged.  This new breed may not have set career goals to become project managers, many among them do not even consider themselves to be project managers, but they do know that they must successfully manage projects to move ahead in their careers.  Clearly, project management has become a critical skill for many, not just a career choice for a few.”
Nick Graham, Stanley E. Portny in Project Management for Dummies

“…It’s good to think in terms of the physics approach, the first principles.  Which is rather than reasoning by analogy, you boil things down to the most fundamental proofs you can imagine, and you reason up from there.  And this is a good way to figure out if, if something really makes sense, or if it’s just what everyone else is doing.”
Elon Musk

“You cannot let a fear of failure, or a fear of comparison, or a fear of judgment stop you from doing what’s going to make you great.  You cannot succeed without this risk of failure; you cannot have a voice without the risk of criticism; and you cannot love without the risk of loss.  You must go out and you must take these risks…And people will tell you to do what makes you happy, but a lot of this has been hard work, and I’m not always happy.  And I don’t think you should do just what makes you happy; I think you should do what makes you great.  Do what’s uncomfortable, and scary, and hard, but pays off in the long run.  Be willing to fail; let yourself fail; fail in the way and the place where you would want to fail.  Fail, pick yourself up and fail again.  Because without this struggle, what is your success anyway?
As best we know it, we have one life. In it you have to trust your own voice, your own ideas, your honesty, your vulnerability, and through this you will find your way.  You do not have to be fearless, just don’t let fear stop you.  Live like this as best you can and I guarantee you will look back on a life well lived.”
Charlie Day, Merrimack College Commencement Address, 2014

“I am not an advocate for frequent changes in laws and constitutions, but laws and institutions must go hand in hand with the progress of the human mind.  As that becomes more developed, more enlightened, as new discoveries are made, new truths discovered and manners and opinions change, with the change of circumstances, institutions must advance also to keep pace with the times.  We might as well require a man to wear still the coat which fitted him when a boy as civilized society to remain ever under the regimen of their barbarous ancestors.”
Thomas Jefferson

“Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them: the starry heavens above me and the moral law within me. I do not seek or conjecture either of them as if they were veiled obscurities or extravagances beyond the horizon of my vision; I see them before me and connect them immediately with the consciousness of my existence.”
Immanuel Kant, Critique of Practical Reason, 1788
