I just finished "The 48 Laws of Power," which - as a former hater of learning history - I have learned to love the lessons that history can provide. As my next challenge, I've started reading Meditations by Marcus Aurelius recently to continue challenging myself to learn more from the books that is spend my spare time with. Here is a particularly good quote:
"Remember how long you have been putting off these things, and how many times the gods have given you days of grace, and yet you do not use them. Now is it high time to perceive the kind of Universe whereof you are a part and the nature of the governor of the Universe from whom you subsist as an effluence, and that the term of your time is circumscribed, and that unless you use it to attain calm of mind, time will be gone and you will be gone and the opportunity to use it will not be yours again." - Marcus Aurelius Antoninus
I love this quote because it puts into context the way we all use our "free" time. Although he mentions "days of grace" the thought can be applied to "hours of grace" or "minutes of grace" in maximizing our own happiness, be it in the form of learning new things, helping others, practicing a hobby, etc. The quote particularly resonated with me because of the book/knowledge journey I am beginning, whose benefits are unforeseeable and timing is unknowable.
