These are some great things for all of us to ruminate about. I can tell you from experience, it doesn't get any easier as you continue down the path of life. In fact, I'd argue a lot of people are more toxic in their later years than in their twenties—if they haven't worked on themselves, been honest with themselves, and are aiming for the highest good (striving to be the best versions of themselves as they can be). I agree, this last one is the most important and impactful one.
I was just thinking last night on my walk about how important reading from a daily reader has been for keeping me on the path and being my best self since the Pandemic. I've read from a few throughout life but the best I've found for me are 365 Tao: Daily Meditations and The Daily Stoic by Ryan Holiday.
There's something quite serendipitous that happens when you're consistent with a daily reader. It's often like the passage you're reading that day is in perfect alignment with what you need in that moment. It's been a tremendous help for me during one of the most challenging times of my life. Along with meditation both of these books have been like a buoy that have kept me afloat and actually striving most days.
It's always great to read you! Enjoy the day (or should I say night in your part of the world).
