Krishnamurti has this definition of suffering that I really like, “Suffering is that moment when you see reality exactly as it is. When you can no longer run away from it, when you can no longer deny it.”~ Naval Ravikant from, https://tim.blog/2015/08/18/the-evolutionary-angel-naval-ravikant/
I don’t know anything about Krishnamurti. But I know a good statement that cuts right through all the day-to-day bullshit; That right there is one.
I’ll save you some digging: Naval is quoting Jiddu Krishnamurti, apparently from The Book of Life: Daily Meditations.
…also, go listen to this entire podcast. It’s insanely long at 2+ hours, but Naval is a real down-to-Earth guy with a lot of useful advice on how to live.
