Life is complicated and messy sometimes. It doesn't take much to land yourself in a challenging set of circumstances; we all have our stuff. Some people have more than others, but I know very few people who get through 80-100 years without some serious difficulty along the way. In fact, I don't know anyone.
I have a saying that peace is an active state of mind. We're trying to combine the sense of peace with the necessity for constant work. Peace was often defined as something languid and laid back, a state where you can fold your tent up, stop making an effort, and stop being vigilant. That's not what peace is.
