Lesson #1, and maybe the only one we need to learn...
"Life is Suffering." - Buddha
Yeah. No way around suffering. We all suffer. We can't solve suffering, we can't avoid it, or talk our way out of it. There is no denying. Life is suffering.
You get the idea.
We must live with suffering. Learn to live with suffering. And still carry on. Not move past, not deny, just live with suffering as best we can.
