This is one of my favorite Marcus Aurelius quotes as it reminds us that whatever situation that we find ourselves in, it's a perfect chance to practice our philosophy.
The question is, what area of your life do you find yourself in that's a good opportunity to practice your philosophy?
For me, it's been the practice of working consistently and not getting distracted. When I get bored and distract myself from what I am meant to do, it's a good opportunity to focus on the present and do what needs to be done.
