How Do You Surrender?

How do you understand that everything is going to work out, even when things aren't working out? For me it's about just letting unfold what is going to unfold. It's like giving yourself a little tests every day. In another way is to notice bad things happen and then track the results of those bad things happening. That's how you continue along that process. I don't know if that answers your question, but that was my take aways. O, i have a follow up though. Where did that stem from? Te the being able to assupt it a cause.
