more on that learning curve

This is a quote from a book I’m reading:

“Mastering singleness is sometimes a slow and thoughtful process. It requires contemplation. Our lives are no one’s responsibility but our own. There are many things that we have no control over, and those things we are not responsible for. But we are responsible for how we respond to our own circumstances. Dwelling on the past won’t undo what is already gone, and fretting about the future won’t change what’s coming.”
